Chemical Structure
Description
CATO supplies 4,5-Bis(thiophen-2-yl)-1h-imidazole-2-thiol (CAS 67947-42-6), a certified reference material (molecular formula C11H8N2S3, MW 264.39 g/mol) for analytical method development and quality control.
4,5-Bis(thiophen-2-yl)-1h-imidazole-2-thiol (C11H8N2S3) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality. Its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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 4,5-Bis(thiophen-2-yl)-1h-imidazole-2-thiol 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.
