D-Norvaline CAS 2013-12-9

1. D-Norvaline is a non-proteinogenic D-amino acid primarily used in biochemical research as a tool to study the specificity of enzymes that metabolize natural branched-chain amino acids .
2. D-Norvaline CAS 2013-12-9 serves as a substrate for D-amino acid oxidase and other enzymes involved in D-amino acid metabolism, and is used in studies investigating the role of D-amino acids in bacterial physiology and neurotransmission .
3. D-Norvaline is employed in peptide synthesis to create D-amino acid-containing peptides with enhanced metabolic stability and protease resistance compared to their L-counterparts .
4. Researchers utilize D-Norvaline CAS 2013-12-9 as a chiral building block in asymmetric synthesis and as a tool for studying stereospecific biological interactions .

1. D-Norvaline must be stored in a tightly sealed container in a cool, dry, and well-ventilated environment, protected from light and moisture; powder is stable for up to 3 years at -20°C or 2 years at 4°C .
2. D-Norvaline CAS 2013-12-9 is classified with GHS hazard statements H315 (Causes skin irritation), H319 (Causes serious eye irritation), and H335 (May cause respiratory irritation), with signal word "Warning" .
3. Personnel must wear chemical-resistant gloves, safety goggles with side-shields, and protective clothing when handling this substance, ensuring adequate ventilation in work areas .
4. Keep D-Norvaline CAS 2013-12-9 away from incompatible materials such as strong oxidizing agents; 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 D-Norvaline is released .
2. Collect D-Norvaline CAS 2013-12-9 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 through licensed chemical destruction or controlled incineration .

1. D-Norvaline is not classified as highly flammable but may decompose under fire conditions, emitting toxic fumes including 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 D-Norvaline CAS 2013-12-9 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 D-Norvaline 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 .
