Description

CATO supplies 51605-32-4 ET2TR8P0QG NSC-195976 Ethyl 4-methylimidazole-5-carboxylate 1H-Imidazole-5-carboxylic acid, 4-methyl-, ethyl ester 1H-Imidazole-4-carboxylic acid, 5-methyl-, ethyl ester 4-Carboethoxy-5-methylimidazole EINECS 257-315-3 NSC 195976 UNII-ET2TR8P0QG (CAS 51605-32-4), a certified reference material (molecular formula C7H14N2O2, MW 158.20 g/mol) for analytical method development and quality control.

Based on its molecular formula C7H14N2O2, 51605-32-4 ET2TR8P0QG NSC-195976 Ethyl 4-methylimidazole-5-carboxylate 1H-Imidazole-5-carboxylic acid, 4-methyl-, ethyl ester 1H-Imidazole-4-carboxylic acid, 5-methyl-, ethyl ester 4-Carboethoxy-5-methylimidazole EINECS 257-315-3 NSC 195976 UNII-ET2TR8P0QG contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 158.20 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

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.
