Chemical Structure
Description
The molecular framework of 2-Amino-3-(1H-imidazol-4-yl)propanoic acid hydrochloride hydrate (C6H9N3O2HClH2O) is characterized by an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
CATO supplies 2-Amino-3-(1H-imidazol-4-yl)propanoic acid hydrochloride hydrate (CAS 123333-71-1), a certified reference material (molecular formula C6H9N3O2HClH2O, MW 209.63 g/mol) for analytical method development and quality control.
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.
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.
