Chemical Structure
Description
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
(S)-Ethyl 2-amino-3-(1H-imidazol-4-yl)propanoate hydrochloride (CAS 68636-91-9) is a high-purity analytical reference standard with the molecular formula C8H13N3O2HCl and a molecular weight of 219.67 g/mol.
(S)-Ethyl 2-amino-3-(1H-imidazol-4-yl)propanoate hydrochloride (C8H13N3O2HCl) 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
