Description

D-Threonine(Bzl)-Obzl Oxalate (1:1) is a protected derivative of the amino acid threonine, specifically formulated as an oxalate salt. This high-purity building block is critical for the synthesis of complex peptides and pharmaceutical intermediates where precise stereochemistry and side-chain protection are required. It is primarily utilized by research institutions and manufacturers in the pharmaceutical, biotechnology, and fine chemical sectors for advanced R&D and cGMP production.

Application

• Pharmaceutical Intermediate: A key chiral building block in the synthesis of novel therapeutic peptides and active pharmaceutical ingredients (APIs).
• Peptide Synthesis: Used in solid-phase and solution-phase peptide synthesis (SPPS) to incorporate protected threonine residues into peptide chains.
• Biochemical Research: Serves as a reagent in proteomics research, enzyme studies, and the development of biochemical probes.
• Fine Chemical Production: Employed in the multi-step synthesis of complex organic molecules requiring protected amino acid motifs.
• Reference Standard: Can be used as a high-purity analytical standard for quality control and method development in analytical laboratories.
