Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies 4-Chloro-2-(2-chlorophenyl)-1H-imidazo[4,5-c]pyridine (CAS 77712-91-5), a certified reference material (molecular formula C12H7Cl2N3, MW 264.11 g/mol) for analytical method development and quality control.
The molecular framework of 4-Chloro-2-(2-chlorophenyl)-1H-imidazo[4,5-c]pyridine (C12H7Cl2N3) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution. 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).
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.
