DL-Aspartic Acid CAS 617-45-8

1. DL-Aspartic acid is a racemic mixture of the amino acid aspartic acid, used as a fundamental building block in biochemical research and as a precursor in peptide synthesis .
2. DL-Aspartic acid CAS 617-45-8 serves as a substrate and analytical standard in studies of amino acid metabolism, enzymatic reactions, and protein synthesis mechanisms .
3. DL-Aspartic acid is employed in nutritional research and as a component in cell culture media formulations .
4. Researchers utilize DL-Aspartic acid CAS 617-45-8 for R&D purposes, where its balanced stereochemistry makes it valuable for studying racemic mixtures in various biological and chemical systems .

1. DL-Aspartic acid must be stored in a tightly sealed container in a cool, dry, and well-ventilated environment; recommended storage at room temperature in a cool, dark place or at -20°C for long-term stability .
2. DL-Aspartic acid CAS 617-45-8 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 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-Aspartic acid is released .
2. Collect DL-Aspartic acid CAS 617-45-8 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; 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. DL-Aspartic acid 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-Aspartic acid CAS 617-45-8 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-Aspartic acid 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 .
