Description

CATO manufactures 2-(6-Chloropyridin-3-yl)-1-[(3,4-dichlorophenyl)methyl]-5,6-dimethyl-1H-1,3-benzodiazole 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.

CATO supplies 2-(6-Chloropyridin-3-yl)-1-[(3,4-dichlorophenyl)methyl]-5,6-dimethyl-1H-1,3-benzodiazole (CAS 337920-65-7), a certified reference material (molecular formula C21H16Cl3N3, MW 416.73 g/mol) for analytical method development and quality control.

Structurally, 2-(6-Chloropyridin-3-yl)-1-[(3,4-dichlorophenyl)methyl]-5,6-dimethyl-1H-1,3-benzodiazole (C21H16Cl3N3) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 14.0, corresponding to approximately 14 ring(s) or double-bond equivalent(s). With a molecular weight of 416.73 g/mol, it falls into the moderately-high-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.
