DL-Pyroglutamic acid (CAS# 149-87-1) introduction
DL pyroglutamic acid is an amino acid, also known as DL-2-aminoglutaric acid. DL pyroglutamic acid is a colorless crystalline powder that is soluble in water and ethanol.

There are usually two methods for producing DL pyroglutamic acid: chemical synthesis and microbial fermentation. Chemical synthesis is obtained by reacting appropriate compounds, while microbial fermentation utilizes specific microorganisms to metabolize and synthesize the amino acid.

Safety information for DL pyroglutamic acid: It is considered a relatively safe compound with no apparent toxicity. As a chemical, it should be stored and used under appropriate conditions, avoiding contact with strong oxidants. Before using DL pyroglutamic acid, it should be handled according to the correct operating procedures and personal protective measures.
