General description

L-Alanine methyl ester hydrochloride also known as L-Ala-OMe·HCl, is a versatile reagent used commonly in solution phase peptide synthesis. It is often used to synthesize dipeptides.

Application

L-Alanine methyl ester hydrochloride can be used as a starting material in the synthesis of alanine isoxazolidide via solution phase peptide synthesis. Additionally, it is used to synthesize N-Fmoc-l-alanyl-l-alanine methyl ester and α-amino acid-based sector block dendrons.
