Chemical Structure
Description
As a certified reference material (CRM), 4-Ethyl-2-methyl-1H-imidazole-5-carboxylic acid hydrochloride meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
CATO supplies 4-Ethyl-2-methyl-1H-imidazole-5-carboxylic acid hydrochloride (CAS 2287310-33-0), a certified reference material (molecular formula C7H10N2O2HCl, MW 190.63 g/mol) for analytical method development and quality control.
The molecular framework of 4-Ethyl-2-methyl-1H-imidazole-5-carboxylic acid hydrochloride (C7H10N2O2HCl) 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
