Chemical Structure
Description
4-chloro-2-methyl-3H-imidazo[4,5-c]pyridine (CAS 50432-65-0) is a high-purity analytical reference standard with the molecular formula C7H6ClN3 and a molecular weight of 167.60 g/mol.
4-chloro-2-methyl-3H-imidazo[4,5-c]pyridine (C7H6ClN3) contains a nitrile group, chlorine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point; 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.
CATO manufactures 4-chloro-2-methyl-3H-imidazo[4,5-c]pyridine under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
