D-Threonine CAS 632-20-2

1. D-Threonine is a non-proteinogenic D-amino acid used in biochemical research to study stereospecific biological interactions, particularly in relation to bacterial cell wall synthesis and D-amino acid metabolism .
2. D-Threonine CAS 632-20-2 serves as a negative control in studies investigating the biological activity of L-threonine, and is employed in research on D-amino acid oxidase and other enzymes involved in D-amino acid metabolism .
3. D-Threonine is utilized in peptide synthesis to create D-amino acid-containing peptides with enhanced metabolic stability and protease resistance compared to their L-counterparts .
4. Researchers employ D-Threonine CAS 632-20-2 as a chiral building block in asymmetric synthesis and as a tool for studying the role of D-amino acids in bacterial physiology and neurotransmission .

1. D-Threonine 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-Threonine CAS 632-20-2 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 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-Threonine is released .
2. Collect D-Threonine CAS 632-20-2 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; prevent D-threonine 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-Threonine 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-Threonine CAS 632-20-2 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-Threonine 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 .
