Glycine methyl ester hydrochloride is the organic compound with the formula [CH₃O₂CCH₂NH₃]Cl. A white, water-soluble solid, it is the hydrochloride of the methyl ester of the amino acid glycine.

Synthesis and reactions

Glycine methyl ester hydrochloride can be prepared by treatment of glycine with 2 equivalents of trimethylsilyl chloride followed by the addition of methanol.[2][3]

Upon treatment with base, the salt converts to glycine methyl ester.[4]
