Chemical Structure
Description
The molecular framework of Ethyl 5-amino-1H-imidazole-2-carboxylate (hydrochloride) (C6H9N3O2HCl) 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Ethyl 5-amino-1H-imidazole-2-carboxylate (hydrochloride) (CAS 2044901-79-1) is a high-purity analytical reference standard with the molecular formula C6H9N3O2HCl and a molecular weight of 191.62 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.
