D-Proline CAS 344-25-2

1. D-Proline is primarily used as a valuable chiral building block in the synthesis of enantiomerically pure pharmaceuticals, agrochemicals, and other bioactive compounds .
2. D-Proline CAS 344-25-2 is employed in biocatalysis as a co-factor in the deracemization of racemic amino acids to produce enantiopure D-amino acids .
3. D-Proline serves as a ligand in asymmetric synthesis and chiral catalysis, enabling stereoselective chemical transformations .
4. Researchers utilize D-Proline CAS 344-25-2 this amino acid in peptide synthesis to create D-amino acid-containing peptides with enhanced metabolic stability and protease resistance, and as a standard in amino acid analysis for the food industry .

1. D-Proline must be stored in a tightly sealed container in a cool, dry, and well-ventilated environment; recommended storage at RT (room temperature) or at -20°C for long-term stability, protected from light .
2. D-Proline CAS 344-25-2 is not classified as a hazardous substance or mixture according to 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, strong acids, and strong bases; for solution storage, prepare aliquots in tightly sealed vials and use within 1 month, avoiding repeated freeze-thaw cycles .

1. Isolate the spill area, ensure adequate ventilation, and wear full personal protective equipment including chemical-resistant gloves and safety goggles when D-Proline is released .
2. Collect D-Proline CAS 344-25-2 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 as non-hazardous waste according to local, state, and federal environmental regulations through licensed chemical destruction or controlled incineration .

1. D-Proline is not classified as highly flammable (NFPA fire rating of 1) with a melting point >200°C (dec.); under fire conditions, hazardous decomposition products include toxic fumes of carbon monoxide, carbon dioxide, and nitrogen oxides (NOx) .
2. Use D-Proline CAS 344-25-2 water spray, dry chemical powder, carbon dioxide, or alcohol-resistant foam to extinguish fires involving the product .
3. Firefighters should wear self-contained breathing apparatus in pressure-demand, MSHA/NIOSH approved, and full protective gear when handling burning D-Proline 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 .
