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 4-(Chloromethyl)-5-methyl-2-(methylthio)-1H-imidazole (CAS 787511-01-7), a certified reference material (molecular formula C6H9ClN2S, MW 176.67 g/mol) for analytical method development and quality control.
The molecular framework of 4-(Chloromethyl)-5-methyl-2-(methylthio)-1H-imidazole (C6H9ClN2S) is characterized by a nitrile group, sulfur-containing functionality, 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), 4-(Chloromethyl)-5-methyl-2-(methylthio)-1H-imidazole 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.
