N-Acetyl-L-tryptophan CAS 1218-34-4

1. N-Acetyl-L-tryptophan CAS 1218-34-4 is a derivative of the essential amino acid tryptophan, where the amino group is acetylated, serving as a stabilized form in biochemical research and pharmaceutical development .
2. N-Acetyl-L-tryptophan is employed as a building block in peptide synthesis, particularly for incorporating tryptophan residues while protecting the amino group during chain elongation .
3. N-Acetyl-L-tryptophan functions as a substrate in enzymatic studies investigating tryptophan metabolism, acetylation/deacetylation pathways, and protein modification mechanisms .
4. Researchers utilize N-Acetyl-L-tryptophan as a reference standard in analytical chemistry for amino acid analysis and as a research tool for studying the role of acetylation in protein function and stability .

1. N-Acetyl-L-tryptophan CAS 1218-34-4 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. N-Acetyl-L-tryptophan 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 and 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 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 N-Acetyl-L-tryptophan CAS 1218-34-4 is released .
2. Collect N-Acetyl-L-tryptophan 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 as discharge into the environment should be avoided .
4. Dispose of collected material according to local, state, and federal environmental regulations through licensed chemical destruction or controlled incineration .

1. N-Acetyl-L-tryptophan CAS 1218-34-4 is not classified as highly flammable but may decompose under fire conditions; 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 N-Acetyl-L-tryptophan 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 N-Acetyl-L-tryptophan 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 .
