Application

L-Histidine methyl ester dihydrochloride can be used as a reactant to synthesize:
  • Imidazopyridine derivatives by Pictet-Spegler reaction with different aldehydes.[1]
  • A metal-chelating ligand, N-methacryloyl-(l)-histidine methyl ester by reacting with methacryloyl chloride.[2]
  • Zwitterionic polypeptide derivative by amidation reaction with poly (α,β-L-aspartic acid).[3]
