Our warehouse keeps a steady stock of up to 100 tons, which means that deliveries can happen within 5–8 business days. To meet international pharmacy standards, each batch goes through strict testing by a third party.

Our MOQ is variable, and it starts at 25 kg, which is packed in sealed 25 kg drums. Our expert export department and customer service team are available 24 hours a day, seven days a week to help you with your formulation needs.

What Is N-Acetyl-L-cysteine Ethyl Ester?

The product is a lipophilic form of N-Acetyl-L-cysteine that was made to fix the problems with standard NAC's bioavailability. Standard NAC is only bioavailable in 6–10% when taken by mouth, but this esterified form easily crosses cell membranes without the need for special transporters.

The molecule can effectively pass through lipid bilayers and the blood-brain barrier because the carboxyl group has been esterified. Because of this, it is very useful for uses that need to deliver drugs inside cells that are protected, like those in the brain, heart, and red blood cells.

As a strong precursor to glutathione, NACET helps cells restore their antioxidant stores more effectively than taking glutathione supplements by mouth. It is chosen by researchers and formulators when therapeutic concentrations of standard NAC can't be reached in target tissues.

Product Specifications

Key Advantages for Your Formulations

Better Penetration of Cells

Our product is very good at dissolving in lipids, which lets it pass through cell membranes without needing a transporter. This property makes sure that it is taken up consistently in a wide range of physiological settings, which makes it perfect for systemic uses.

The partition coefficient is much more favourable to lipid environments than normal NAC. This means that your finished products will have higher concentrations inside cells and better therapeutic effects.

Glutathione Precursor That Works Well

NACET is a very good building block for making glutathione (GSH) inside of cells. Cellular esterases cut the ethyl group once it's inside the cell, sending the active NAC form right to where it's needed most.

This way gets around the problems with oral glutathione, which breaks down in the digestive system. Your customers will get better antioxidant protection and better redox balance at the level of the cells.

Making Hydrogen Sulphide

In addition to helping glutathione, this molecule makes hydrogen sulphide (H₂S), which is an important gasotransmitter for cell communication. This two-in-one process makes formulations that target mitochondrial function and longevity more useful.

Quality Control Standards

Every batch of N-Acetyl-L-cysteine Ethyl Ester made at Xi'an DN Biology goes through a lot of tests to make sure it is of pharmaceutical-grade quality. Our separate lab uses HPLC to find impurities and figure out what an assay is, and it always gets results of 99% purity or higher.

We use H-NMR spectroscopy to make sure that the esterified molecule has a stable structure. The FT-IR test checks the functionality of the acetyl and thiol groups, which makes sure the molecule keeps its bioactive qualities.

GC-HS tests for residual solvents makes sure that ICH Q3C rules are followed. During the synthesis process, we keep a close eye on the levels of ethanol and ethyl acetate. ICP-MS tests for Lead, Arsenic, Cadmium, and Mercury, which are all heavy metals, to make sure they meet USP and EP standards.

Ellman's Reagent test measures the amount of active sulfhydryl that determines the antioxidant potential and confirms the thiol group's reactivity. Total Plate Count (TPC <1000 cfu/g) and screening for E. coli, Salmonella, and other pathogens are part of microbial tests.

A Certificate of Analysis is sent with every package. We also offer free samples before shipping to make sure everything is right, and if you need it, we can help with third-party laboratory testing.

Primary Application Areas

High-End Food Supplements

Formulators choose this ingredient for high-end nootropic and longevity supplements because it is more bioavailable, which explains the higher price. Crossing the blood-brain barrier is very important for formulas that are meant to improve brain health.

Your customers who want all-around antioxidant support will like how the intracellular glutathione elevation is better than with regular NAC goods. This means it can be used in formulas for anti-aging and cellular health.

Life Sciences and Pharmaceutical R&D

Researchers who are working on neuroprotective models like NACET because it can get to therapeutic levels in brain tissue. It deals with oxidative stress in neurodegenerative research, where regular NAC doesn't work very well.

Because it is taken up by cells consistently in all types of tissue, it is useful for studies that need to look at antioxidant effects on the whole body. It is stable and pure enough to meet the strict requirements of pharmaceutical research.

Functional Skincare Products

Because it is more permeable through membranes, this compound can be used in topical products that target oxidative damage. Researchers in the cosmetics industry use it in high-tech skin care products that are meant to protect against environmental stressors.

Its ability to raise intracellular glutathione in skin cells makes it useful for formulas that aim to protect cells from UV-induced oxidative damage and help them grow again.

Handling and Storage Guidelines

The powder will stay stable for up to 3 years if you keep it in sealed containers at -20°C and in the dark. The chemical easily oxidizes in air and light, so it's important to store it properly to keep its effectiveness.

Once they are dissolved, make new working solutions if you can. If you need to store something, freeze it at -80°C or -20°C in portions to cut down on the number of freeze-thaw cycles. To keep things safe from light, use amber glass cases.

The powder is easily broken down in water and DMSO (dimethyl sulfoxide), which makes it useful for both research and formulating. To keep oxidation to a minimum in water-based products, you might want to use degassed water and nitrogen overlay.

Loss on drying should stay below 1% to keep things from breaking down too quickly. Our packaging is made to keep these specifications throughout the shelf life as long as it is stored properly.

Packaging and Shipping

As standard, 25 kg is packed in a fibre drum with two food-safe plastic bags inside. Our packing keeps the product stable while it's being shipped and stored.

Custom packaging is available upon request for different amounts or unique needs in terms of containment.

Shipping Options: We offer a range of shipping options, such as DDP, air freight, and sea freight. Our skilled export team takes care of the paperwork and makes sure that customs clearance goes smoothly.

Quality Control: Each package comes with the right labels, an analysis certificate, and a material safety data sheet (MSDS). For partners who are qualified, we can help with on-site factory inspections.

FAQ

Q: What's the difference between NACET and everyday NAC?

A: The ethyl ester change makes it much easier for lipids to dissolve and for cells to pass through. Standard NAC is only 6–10% bioavailable and doesn't pass through cell walls very well. NACET, on the other hand, does this very well without the need for special transporters. This leads to better delivery inside cells and a higher level of glutathione.

Q: How should I deal with products that don't dissolve in water?

A: The compound is easy to dissolve in both DMSO and water, which means it can be used in a wide range of research and commercial formulations. If you need to, use gentle heating for water-based solutions. It works very well with oils and lipid carriers in lipid-based delivery systems because it is more lipophilic.

Q: What kinds of quality checks do you offer?

A: Each batch goes through an HPLC test (≥99%), an H-NMR test to confirm the structure, a GC-HS test to check for residual solvents, an ICP-MS test to check for heavy metals, an Ellman's test to check for thiol content, and microbial testing. We give you a full Certificate of Analysis and allow a third party to check it.

Q: What kind of storage do you need?

A: You can keep powder at -20°C for up to 3 years in containers that are covered and keep light out. Frozen liquids should be kept at -20°C or -80°C. Keep it away from air, light, and moisture as much as possible to keep it from oxidizing and keeping its effectiveness.

Q: How much of an order do I need to place in order for it to be delivered?

A: Our MOQ is 25 kg, which comes in sealed drums. We can send in-stock orders within 5–8 working days after receiving payment confirmation because we keep our stock at a steady level of up to 100 tons. For production scheduling on larger or more specific orders, please get in touch with our team.

Q: Can you help with custom packing or specifications?

A: Yes, we do offer OEM/ODM services for making custom mixes and packing. Our R&D team can use your instructions to come up with solutions that are just right for you. Get in touch with us to talk about your specific needs and production schedules.
