Chemical Structure
Description
CATO supplies 5-Ethynyl-1-methyl-1H-benzo[d]imidazole (CAS 1934871-82-5), a certified reference material (molecular formula C10H8N2, MW 156.18 g/mol) for analytical method development and quality control.
The molecular framework of 5-Ethynyl-1-methyl-1H-benzo[d]imidazole (C10H8N2) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures 5-Ethynyl-1-methyl-1H-benzo[d]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.
