Description
COA-BACKED NUTRITIONAL INGREDIENT
N-Acetyl-L-Cysteine for B2B Formulation
N-Acetyl-L-Cysteine is supplied as a single-entity amino acid for B2B nutrition, beverage and supplement formulation. The purchasing definition is the declared assay, the impurity profile and the physical form rather than a botanical identity.

Buyer Decision Guide
N-Acetyl-L-Cysteine is specified on assay, specific rotation or chiral purity where relevant, and on heavy metal and microbiological limits. Confirm which of these your finished-product specification actually controls before approving a grade.
- Confirm assay basis and analytical method
- Check the salt or free-form identity: N-Acetyl-L-Cysteine
- Review specific rotation or chiral purity if applicable
- Confirm heavy metal and microbiological limits
How This Grade Differs
N-Acetyl-L-Cysteine is a single-entity amino acid. It is not interchangeable with the racemic or salt form of the same molecule, and not with a plant extract that merely contains it. Compare assay basis, salt form and impurity profile when substituting.
Compare these related grades before approval:
For a substitution review, compare N-acetyl-L-cysteine chemical identity, the 98.5%-101.0% HPLC assay on a dried basis, crystalline powder form and the current offered-batch COA. Confirm the named amino-acid derivative before treating another grade as equivalent.

Frequently Asked Questions
Can the COA be matched to the lot you ship?
Yes. The certificate is issued for the shipped lot, which is the batch LXYX260226 referenced on the specification.
How long can we hold stock before use?
Two years when stored properly from the manufacture date when the pack stays sealed and dry.
Can the mesh be adjusted for our process?
Standard supply is 98% through 80 mesh; a different cut is agreed in writing before production.
What physical form does N-Acetyl-L-Cysteine Powder 99% ship in?
Fine white crystalline powder, milled to 98% through 80 mesh.
How is N-Acetyl-L-Cysteine Powder 99% quantified?
By HPLC against the specification figure of 98.5%-101.0% on dried basis.
Can I get a sample before placing the order?
Yes. An evaluation sample is normally available before a formal order. Sample quantity, courier account and destination are confirmed at the time of request.
What packing options are available?
Standard packing is a sealed food-grade inner liner inside an export carton or fibre drum. Pack size, labelling and private-label artwork are agreed in the written specification.
What is the usual lead time?
Regular production normally takes 7-15 working days after deposit, depending on stock, volume, testing and customisation requirements.
