Chemical Structure
Description
1-(3,5-Dimethylphenyl)-3-methylbenzo[4,5]imidazo[1,2-a]pyridine-4-carbonitrile (CAS 730950-13-7), molecular formula C21H17N3 and molecular weight 311.38 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 1-(3,5-Dimethylphenyl)-3-methylbenzo[4,5]imidazo[1,2-a]pyridine-4-carbonitrile (C21H17N3) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), 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).
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.
