Chemical Structure

5-Amino-1H-imidazo[4,5-b]pyridine-6-carbonitrile CAS 50738-98-2 chemical structure

Description

5-Amino-1H-imidazo[4,5-b]pyridine-6-carbonitrile (CAS 50738-98-2), molecular formula C7H5N5 and molecular weight 159.15 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 5-Amino-1H-imidazo[4,5-b]pyridine-6-carbonitrile (C7H5N5) is characterized by a nitrile group, an aromatic ring system. 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. 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.
