1-Amino-3-(4-(tert-butyl)phenyl)benzo[4,5]imidazo[1,2-a]pyridine-2,4-dicarbonitrile CAS 885458-42-4

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1-Amino-3-(4-(tert-butyl)phenyl)benzo[4,5]imidazo[1,2-a]pyridine-2,4-dicarbonitrile.

1-Amino-3-(4-(tert-butyl)phenyl)benzo[4,5]imidazo[1,2-a]pyridine-2,4-dicarbonitrile (CAS 885458-42-4), molecular formula C23H19N5 and molecular weight 365.43 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C23H19N5, 1-Amino-3-(4-(tert-butyl)phenyl)benzo[4,5]imidazo[1,2-a]pyridine-2,4-dicarbonitrile contains a nitrogen-containing heterocyclic scaffold, a nitrile group; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 365.43 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.

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.
