4-(3-(4-Chlorophenyl)-1H-1,2,4-triazol-5-yl)pyridine CAS 36646-40-9 chemical structure

Description

The occurrence of 4-(3-(4-Chlorophenyl)-1H-1,2,4-triazol-5-yl)pyridine is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 4-(3-(4-Chlorophenyl)-1H-1,2,4-triazol-5-yl)pyridine (CAS 36646-40-9), a certified reference material (molecular formula C13H9ClN4, MW 256.69 g/mol) for analytical method development and quality control.

The molecular framework of 4-(3-(4-Chlorophenyl)-1H-1,2,4-triazol-5-yl)pyridine (C13H9ClN4) 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

CATO manufactures 4-(3-(4-Chlorophenyl)-1H-1,2,4-triazol-5-yl)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.
