Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2H-Benzo[d]imidazole-2-thione.
CATO supplies 2H-Benzo[d]imidazole-2-thione (CAS 58536-70-2), a certified reference material (molecular formula C7H4N2S, MW 148.19 g/mol) for analytical method development and quality control.
The molecular framework of 2H-Benzo[d]imidazole-2-thione (C7H4N2S) is characterized by a nitrile group, sulfur-containing functionality, an aromatic ring system. 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 2H-Benzo[d]imidazole-2-thione 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.
