N-Acetyl-DL-Methionine (CAS 1115-47-5), min. 99.0%, supplied wholesale by Zyntex. Stable methionine derivative for enzymatic L-methionine production, specialty feeds and pharmaceutical formulations. CoA and SDS with every lot.
N-Acetyl-DL-methionine (C7H13NO3S) is a white crystalline powder that dissolves in water. Acetylation of the amino group makes it more stable than free methionine and changes its solubility and handling.
Amino acid producers use it as the substrate for enzymatic resolution: an aminoacylase enzyme selectively deacetylates the L-form, giving pure L-methionine for pharmaceutical and food use, while the remaining D-form is recycled. It is also used as a methionine source in specialty feed and nutrition applications and in pharmaceutical formulations.
For the standard feed-grade amino acid, see DL-Methionine; related feed amino acids and additives include L-Threonine and Betaine Hydrochloride.

⚠️ Safety & Handling: Not classified as hazardous under GHS. Avoid dust formation and contact with eyes. Store in tightly closed containers in a cool, dry place. Always consult the Safety Data Sheet (SDS) for full classification and handling instructions.
How is L-methionine produced from N-acetyl-DL-methionine?
An aminoacylase enzyme removes the acetyl group only from the L-form, which can then be separated as pure L-methionine. The D-form is racemized and reused.
What is the difference from DL-methionine?
DL-methionine is the free amino acid used widely in feed, while the N-acetyl form is more stable and mainly used as a substrate and in specialty applications.
