Boc-L-Proline Methyl Ester (CAS 59936-29-7) is a colorless to light yellow liquid, serving as a key, protected amino acid building block in peptide synthesis and pharmaceutical drug development. Commonly used in solution-phase peptide synthesis and to prepare Proline derivatives, it is favored for its purity (≄99%) and stability in forming complex molecules, particularly in developing enzyme inhibitors

 

Uses and Applications

  • Peptide Synthesis: Serves as a protected, activated amino acid intermediate in solid-phase and solution-phase synthesis for creating Proline-containing peptides.
  • Pharmaceutical Development: Key intermediate in synthesizing peptidomimetics and bioactive molecules, particularly in designing enzyme inhibitors.
  • Chemical Research: Utilized in studies requiring chiral, N-protected amino acid derivatives.
  • Bioconjugation: Used as a building block for specialized, tailored amino acid structures in advanced biological research.

Safety and Handling

  • Classification: No hazardous classification required under typical US OSHA regulations.
  • Storage: Generally stored at room temperature or 2–8°C; stable under recommended conditions.
