N-Acetyl-L-methionine CAS 65-82-7

1. N-Acetyl-L-methionine is a protected amino acid derivative used as a source of methionine in nutritional and biochemical research, where the acetyl group enhances stability and bioavailability .
2. N-Acetyl-L-methionine CAS 65-82-7 is employed as a building block in peptide synthesis, particularly in solution-phase and solid-phase peptide synthesis, where it serves as a precursor for incorporating methionine residues .
3. N-Acetyl-L-methionine functions as a substrate in enzymatic studies and metabolic research, serving as an acetyl donor and participating in acetylation/deacetylation pathway investigations .
4. Researchers utilize this product in studies of methionine metabolism and as a reference standard in analytical methods for amino acid analysis and quality control applications .

1. N-Acetyl-L-methionine must be stored in a tightly sealed container in a cool, dry, and well-ventilated environment; powder form is stable for up to 3 years at -20°C or 2 years at 4°C .
2. N-Acetyl-L-methionine CAS 65-82-7 is generally not classified as a hazardous substance under GHS criteria; however, it may cause skin, eye, and respiratory tract irritation, and should be handled with appropriate precautions .
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 to prevent decomposition; for solution storage, prepare aliquots and use within 1 month at -20°C, avoiding repeated freeze-thaw cycles .

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 N-Acetyl-L-methionine is released .
2. Collect N-Acetyl-L-methionine CAS 65-82-7 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; no special environmental precautions are required, but discharge into drains should be prevented .
4. Dispose of collected material according to local, state, and federal environmental regulations, offering surplus and non-recyclable solutions to a licensed disposal company .

1. N-Acetyl-L-methionine is not classified as highly flammable; under fire conditions, hazardous decomposition products include toxic fumes of 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 N-Acetyl-L-methionine CAS 65-82-7 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 N-Acetyl-L-methionine due to hazardous decomposition gases generated by thermal decomposition .
4. During combustion, may emit irritant and toxic fumes; move containers from the fire area if safe to do so, and contain fire runoff to prevent environmental contamination .
