3-(2-(Carboxymethyl)-5-phenyl-1H-imidazol-4-yl)pyridine 1-oxide CAS 87752-81-6 chemical structure

Description

The occurrence of 3-(2-(Carboxymethyl)-5-phenyl-1H-imidazol-4-yl)pyridine 1-oxide is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

3-(2-(Carboxymethyl)-5-phenyl-1H-imidazol-4-yl)pyridine 1-oxide (CAS 87752-81-6), molecular formula C16H13N3O3 and molecular weight 295.29 g/mol, is a CATO reference standard with documented purity and traceability.

3-(2-(Carboxymethyl)-5-phenyl-1H-imidazol-4-yl)pyridine 1-oxide (C16H13N3O3) contains a nitrogen-containing heterocyclic scaffold, 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.

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.
