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.
5-(Chloromethyl)-1-methyl-1H-1,2,4-triazole Hydrochloride (CAS 104256-69-1) is a high-purity analytical reference standard with the molecular formula C4H6ClN3HCl and a molecular weight of 168.02 g/mol.
The molecular framework of 5-(Chloromethyl)-1-methyl-1H-1,2,4-triazole Hydrochloride (C4H6ClN3HCl) is characterized by a nitrile group, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, 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.
As a certified reference material (CRM), 5-(Chloromethyl)-1-methyl-1H-1,2,4-triazole Hydrochloride meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
