D-Homoserine CAS 6027-21-0

1. D-Homoserine CAS 6027-21-0 is primarily used as a building block in chemical synthesis and pharmaceutical research, serving as a precursor for the preparation of various amino acids, peptides, and heterocyclic compounds .
2. D-Homoserine is employed in the synthesis of bacterial polysaccharides, such as the O-antigen of *Acinetobacter lwoffii* EK30A, and is used to produce atypical serine proteases for mechanism studies .
3. D-Homoserine is utilized in peptide synthesis applications, where its unique structure as a D-alpha-amino acid enables the creation of peptides with enhanced metabolic stability .
4. Researchers employ D-Homoserine as a valuable tool for organic chemists seeking to create novel compounds and explore new avenues in chemical synthesis .

1. D-Homoserine CAS 6027-21-0 must be stored in a tightly sealed container in a cool, dry, and well-ventilated environment; powder form is stable for up to 3 years at -20°C or 2 years at 4°C, while solutions should be stored at -80°C for up to 6 months or -20°C for 1 month .
2. D-Homoserine CAS 6027-21-0 is classified with GHS signal word "Warning" and hazard statements including H315 (Causes skin irritation), H319 (Causes serious eye irritation), and H335 (May cause respiratory irritation) .
3. Personnel must wear chemical-resistant rubber gloves, NIOSH/MSHA-approved respirators, chemical safety goggles, and protective clothing when handling this substance, ensuring adequate ventilation in work areas and avoiding formation of dust and aerosols .
4. Keep away from incompatible materials such as strong oxidizing agents; avoid heat and light exposure; and wash thoroughly after handling .

1. Isolate the spill area, ensure adequate ventilation, and wear full personal protective equipment including chemical-resistant rubber gloves, chemical safety goggles, and NIOSH/MSHA-approved respirator when D-Homoserine CAS 6027-21-0 is released .
2. Collect D-Homoserine by sweeping or vacuuming without creating dust using non-sparking tools; for liquid spills, absorb with finely-powdered liquid-binding materials such as diatomite or universal binders, and place into suitable closed containers for disposal .
3. Avoid creating dust clouds during cleanup to prevent respiratory exposure; decontaminate surfaces and equipment by scrubbing with alcohol .
4. Dispose of collected D-Homoserine material as non-hazardous waste according to local, state, and federal environmental regulations, as the substance is considered non-dangerous for transport and does not require special disposal considerations under normal conditions .

1. D-Homoserine CAS 6027-21-0 is not classified as highly flammable but may decompose under fire conditions, with a flash point of approximately 176.8°C and boiling point of 368.7°C at 760 mmHg; hazardous decomposition products include toxic fumes of nitrogen oxides, carbon monoxide, carbon dioxide, and irritating gases .
2. Use D-Homoserine water spray, dry chemical powder, carbon dioxide, or alcohol-resistant foam to extinguish fires involving the product, selecting the extinguishing media appropriate for surrounding materials .
3. Firefighters should wear self-contained breathing apparatus in pressure-demand, MSHA/NIOSH approved, and full protective gear when handling burning D-Homoserine due to hazardous decomposition gases generated by thermal decomposition .
4. During combustion, may D-Homoserine emit irritant and toxic fumes; move containers from the fire area if safe to do so, cool exposed containers with water spray from a protected location, and contain fire runoff to prevent environmental contamination .
