Application
1. DL-Methionine is a racemic mixture of the essential sulfur-containing amino acid methionine, used as a dietary supplement in animal feed to improve growth performance and feed efficiency .
2. DL-methionine CAS 59-51-8 serves as a key intermediate in the synthesis of methionine derivatives and as a building block in peptide synthesis and biochemical research .
3. DL-Methionine is employed as a reference standard in amino acid analysis and as a substrate in studies of methionine metabolism, methylation reactions, and antioxidant pathways .
4. Researchers utilize DL-methionine CAS 59-51-8 for R&D purposes, where its balanced stereochemistry makes it valuable for studying racemic mixtures in various biological and chemical systems .
Storage and Precautions
1. DL-Methionine must be stored in a tightly sealed container in a cool, dry, and well-ventilated environment, protected from light and moisture; recommended storage at room temperature in a cool, dark place .
2. DL-methionine CAS 59-51-8 is generally not classified as a hazardous substance under GHS criteria, but may cause mild skin, eye, and respiratory tract irritation .
3. Personnel should wear chemical-resistant gloves, safety goggles with side-shields, and protective clothing when handling this substance, avoiding formation of dust and aerosols .
4. Keep away from incompatible materials such as strong oxidizing agents, strong acids, and strong bases to prevent decomposition .
Emergency response to leakage
1. Isolate the spill area, ensure adequate ventilation, and wear full personal protective equipment including chemical-resistant gloves, safety goggles, and suitable dust respirator when DL-Methionine is released .
2. Collect DL-methionine CAS 59-51-8 by sweeping or vacuuming without creating dust using non-sparking tools, and place into suitable closed containers for disposal .
3. Avoid creating dust clouds during cleanup to prevent respiratory exposure; prevent the product from entering drains or water courses .
4. Dispose of collected material according to local, state, and federal environmental regulations; the substance is considered non-hazardous for transport .
Fire prevention measures
1. DL-Methionine is not classified as highly flammable but may decompose under fire conditions, emitting toxic fumes including carbon monoxide, carbon dioxide, nitrogen oxides (NOx), and sulfur oxides .
2. Use water spray, dry chemical powder, carbon dioxide, or alcohol-resistant foam to extinguish fires involving the product; do NOT use a direct water jet as DL-methionine CAS 59-51-8 may scatter burning material .
3. Firefighters should wear self-contained breathing apparatus in pressure-demand, MSHA/NIOSH approved, and full protective gear when handling burning DL-Methionine due to hazardous decomposition gases generated by thermal decomposition .
4. During combustion, may emit irritant and toxic fumes; contain fire runoff to prevent environmental contamination .
