D-Tryptophan Methyl Ester Hydrochloride Powder CAS 14907-27-8

D-Tryptophan Methyl Ester Hydrochloride is a white crystalline powder, a chiral amino acid ester derivative with good water solubility. It serves as a critical building block for peptide synthesis and chiral molecule construction, widely applied in medicinal chemistry research, custom organic synthesis, and the preparation of bioactive small molecules. Common application scenarios include developing peptide drugs, exploring asymmetric catalytic reactions, and synthesizing tryptophan-based chiral pharmaceutical intermediates. Its hydrochloride salt form improves stability and operational convenience versus free base. 

Advanced purification controls enantiomeric excess, related impurities and residual solvents. Strict batch testing ensures consistent chiral purity and reduces synthetic experimental deviations. Each batch is verified via HPLC and optical rotation before release. Store sealed away from light, moisture and heat to prevent hydrolysis and racemization. Reliable packaging protects goods during international shipping for lab research and pilot production.
