Chemical Structure
Description
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 supplies 5-(1-chloroethyl)-3-methyl-1H-1,2,4-triazole hydrochloride (CAS 1909316-89-7), a certified reference material (molecular formula C5H8ClN3HCl, MW 182.05 g/mol) for analytical method development and quality control.
5-(1-chloroethyl)-3-methyl-1H-1,2,4-triazole hydrochloride (C5H8ClN3HCl) 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.
CATO manufactures 5-(1-chloroethyl)-3-methyl-1H-1,2,4-triazole hydrochloride 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.
