Chemical Structure

3,5-Dichloro-1H-1,2,4-triazole CAS 10327-87-4 chemical structure

Description

CATO supplies 3,5-Dichloro-1H-1,2,4-triazole (CAS 10327-87-4), a certified reference material (molecular formula C2HCl2N3, MW 137.96 g/mol) for analytical method development and quality control.

3,5-Dichloro-1H-1,2,4-triazole (C2HCl2N3) contains a nitrile group, chlorine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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 3,5-Dichloro-1H-1,2,4-triazole 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.
