Description

L-Alanine, n-(1,1-Dimethylethyl)- (9Ci) CAS NO 89855-32-3 is a specialized, high-purity tert-butyl-protected derivative of the amino acid L-alanine. This compound is a critical building block in organic synthesis, particularly in peptide chemistry and pharmaceutical research, where it serves as a protected intermediate to prevent unwanted side reactions. It is essential for researchers and manufacturers in the pharmaceutical, biotechnology, and fine chemical sectors who require precise molecular control for developing active pharmaceutical ingredients (APIs) and complex organic molecules.

Application

• Pharmaceutical Intermediate: A key protected amino acid building block for the solid-phase and solution-phase synthesis of novel peptides and peptidomimetics.
• API Development: Used in the research and development of active pharmaceutical ingredients (APIs) where the tert-butyloxycarbonyl (Boc) protecting group is required.
• Bioconjugation: Serves as a precursor for creating linkers and modified amino acids used in antibody-drug conjugates (ADCs) and other bioconjugation strategies.
• Chemical Biology Research: Employed in the synthesis of custom peptides for studying protein-protein interactions, enzyme activity, and cellular processes.
• Fine Chemical Synthesis: Acts as a chiral synthon in the asymmetric synthesis of more complex organic molecules for agrochemicals and specialty chemicals.
