Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies 5-(4-Chlorophenyl)-1H-imidazole-2-thiol (CAS 93103-18-5), a certified reference material (molecular formula C9H7ClN2S, MW 210.68 g/mol) for analytical method development and quality control.
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, chlorine substitution, 5-(4-Chlorophenyl)-1H-imidazole-2-thiol is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 210.68 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
As a certified reference material (CRM), 5-(4-Chlorophenyl)-1H-imidazole-2-thiol 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.
