Description

H-Ala-Obzl Hcl CAS NO 557-83-5 is a protected amino acid derivative, specifically the benzyl ester hydrochloride salt of L-alanine. This compound is a critical building block in peptide synthesis, offering a protected carboxyl group that is stable under standard coupling conditions and can be selectively deprotected. It is essential for researchers and manufacturers in the pharmaceutical, biotechnology, and fine chemical industries who require high-purity intermediates for the development of novel peptides, APIs, and other bioactive molecules.

Application

• Peptide Synthesis: A fundamental building block (Fmoc or Boc strategy) for the solid-phase or solution-phase synthesis of custom peptides and peptide libraries.
• Pharmaceutical Intermediates: Used in the research and production of Active Pharmaceutical Ingredients (APIs) for therapeutic peptides.
• Bioconjugation: Serves as a linker or spacer molecule in the conjugation of peptides to other biomolecules, polymers, or surfaces.
• Biochemical Research: Employed in studying enzyme-substrate interactions, protein folding, and as a standard in analytical method development.
• Fine Chemical Production: Acts as a chiral synthon for the asymmetric synthesis of more complex organic molecules and natural products.
