Description
HIGH-PURITY SPECIALTY INGREDIENT
S-Acetyl-L-Glutathione Powder 98%
S-acetyl-L-glutathione is supplied as a single-entity modified tripeptide at 98.0% by HPLC, released against a batch-specific certificate of analysis. The acetyl group is part of the identity of this grade and distinguishes it from unmodified glutathione, which is a separate product. It is an industrial raw material for further processing and is not a finished consumer product.

Buyer Decision Guide
Agree the assay, the analytical method and the identity confirmation before approval. Confirm that the specification calls for the acetylated form rather than unmodified glutathione, since the two are released on different analytical bases and are sold under closely related names.
- Assay: 98.0% by HPLC, released against the batch COA.
- Identity confirmed as the acetylated form, not unmodified glutathione.
- Impurity profile reported per batch.
- Packing and storage requirement agreed at quotation.
- COA, specification sheet and safety data sheet accompany each shipment.
- Regulatory status, permitted uses and labelling are the buyer’s responsibility for the destination market.
How This Grade Differs
S-acetyl-L-glutathione and unmodified glutathione are separate products sold under similar names. The acetyl group changes the identity, the analytical method and the handling. They are not interchangeable, so confirm which form the specification requires before comparing quotations.
For a substitution review, compare botanical identity, plant part, assay target, analytical method, physical form and the current offered-batch COA.
