Application
1. D-Tryptophan methyl ester hydrochloride is a protected derivative of D-tryptophan used in peptide synthesis to incorporate D-tryptophan residues into peptides with enhanced metabolic stability and protease resistance .
2. D-tryptophan methyl ester hydrochloride serves as a chiral building block in asymmetric synthesis and as a precursor for the preparation of tryptophan-based bioactive molecules .
3. D-Tryptophan methyl ester hydrochloride is employed in pharmaceutical research for the development of enzyme inhibitors, antimicrobial agents, and neuroactive compounds .
4. Researchers utilize D-tryptophan methyl ester hydrochloride as a reference standard in analytical chemistry and as a tool for studying stereospecific interactions in biological systems .
Storage and Precautions
1. D-Tryptophan methyl ester hydrochloride must be stored in a tightly sealed container in a cool, dry, and well-ventilated environment, protected from light and moisture; recommended storage at 2-8°C or at -20°C for long-term stability .
2. D-tryptophan methyl ester hydrochloride CAS 14907-27-8 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-tryptophan methyl ester hydrochloride CAS 14907-27-8 away from incompatible materials such as strong oxidizing agents, strong acids, and strong bases to prevent decomposition; wash thoroughly after handling .
Emergency response to leakage
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-Tryptophan methyl ester hydrochloride is released .
2. Collect D-tryptophan methyl ester hydrochloride 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 .
Fire prevention measures
1. D-Tryptophan methyl ester hydrochloride is not classified as highly flammable but may decompose under fire conditions, emitting toxic fumes including carbon monoxide, carbon dioxide, nitrogen oxides (NOx), and hydrogen chloride .
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-tryptophan methyl ester hydrochloride 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-Tryptophan methyl ester hydrochloride 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 .
