Chemical Structure
Description
CATO manufactures 5-(Chloromethyl)-2-ethyl-1H-imidazole 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.
CATO supplies 5-(Chloromethyl)-2-ethyl-1H-imidazole (CAS 1263281-83-9), a certified reference material (molecular formula C6H9ClN2, MW 144.60 g/mol) for analytical method development and quality control.
Owing to a nitrile group, chlorine substitution, 5-(Chloromethyl)-2-ethyl-1H-imidazole is typically white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 144.60 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
