Description

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

CATO supplies 3304-70-9 1H-Imidazole-4,5-dicarboxylic acid, 4,5-dimethyl ester 1H-Imidazole-4,5-dicarboxylic acid, dimethyl ester Dimethyl imidazole-4,5-dicarboxylate Imidazole-4,5-dicarboxylic acid, dimethyl ester NSC 44628 NSC 44693 (CAS 3304-70-9), a certified reference material (molecular formula C7H12N2O4, MW 188.18 g/mol) for analytical method development and quality control.

3304-70-9 1H-Imidazole-4,5-dicarboxylic acid, 4,5-dimethyl ester 1H-Imidazole-4,5-dicarboxylic acid, dimethyl ester Dimethyl imidazole-4,5-dicarboxylate Imidazole-4,5-dicarboxylic acid, dimethyl ester NSC 44628 NSC 44693 (C7H12N2O4) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, 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.

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.
