Chemical Structure
Description
Methyl (S)-2-amino-3-hydroxy-2-methylpropanoate hydrochloride (C5H11NO3HCl) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Methyl (S)-2-amino-3-hydroxy-2-methylpropanoate hydrochloride (CAS 114396-63-3) is a high-purity analytical reference standard with the molecular formula C5H11NO3HCl and a molecular weight of 169.60 g/mol.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
