DL-Alanine CAS 302-72-7

1. DL-Alanine is a racemic mixture of the amino acid alanine, used as a fundamental building block in biochemical research and as a precursor in peptide synthesis and organic chemistry .
2. DL-Alanine CAS 302-72-7 serves as a substrate and analytical standard in studies of amino acid metabolism, enzymatic reactions, and protein synthesis mechanisms .
3. DL-Alanine is employed in nutritional research and as a component in cell culture media formulations .
4. Researchers utilize DL-Alanine CAS 302-72-7 for R&D purposes only, where its balanced stereochemistry makes it valuable for studying racemic mixtures in various biological and chemical systems .

1. DL-Alanine must be stored in a tightly sealed container in a cool, dry, and well-ventilated environment; recommended storage at room temperature (RT) in a cool, dark place or at -20°C for long-term stability .
2. DL-Alanine CAS 302-72-7 is generally not classified as a hazardous substance under GHS criteria, though some sources indicate hazard statements H315 (Causes skin irritation), H319 (Causes serious eye irritation), and H335 (May cause respiratory 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 DL-Alanine CAS 302-72-7 away from incompatible materials such as strong oxidizing agents; for solution storage, prepare aliquots in tightly sealed vials and use within recommended timeframes, 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 DL-Alanine is released .
2. Collect DL-Alanine CAS 302-72-7 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 DL-Alanine CAS 302-72-7 material according to local, state, and federal environmental regulations, offering surplus and non-recyclable solutions to a licensed disposal company .

1. DL-Alanine is not classified as highly flammable with NFPA fire rating of 1 (materials that require considerable preheating before ignition); under fire conditions, hazardous decomposition products include toxic fumes of carbon monoxide, carbon dioxide, and nitrogen oxides (NOx) .
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-Alanine CAS 302-72-7 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 DL-Alanine 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 .
