2-(2-hydroxybenzoyl)pyrido[1,2-a]benzimidazole-4-carbonitrile CAS 190064-61-0

Description

Compared with other compounds in its class, the molecular weight of 313.31 g/mol gives 2-(2-hydroxybenzoyl)pyrido[1,2-a]benzimidazole-4-carbonitrile distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 2-(2-hydroxybenzoyl)pyrido[1,2-a]benzimidazole-4-carbonitrile (CAS 190064-61-0), a certified reference material (molecular formula C19H11N3O2, MW 313.31 g/mol) for analytical method development and quality control.

2-(2-hydroxybenzoyl)pyrido[1,2-a]benzimidazole-4-carbonitrile (C19H11N3O2) contains a steroid core, 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.

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.
