Chemical Structure
Description
The occurrence of 7-Chloro-2,5-bis(trifluoromethyl)-1H-benzo[d]imidazole is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine/chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 7-Chloro-2,5-bis(trifluoromethyl)-1H-benzo[d]imidazole (CAS 1209789-75-2), a certified reference material (molecular formula C9H3ClF6N2, MW 288.58 g/mol) for analytical method development and quality control.
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine/chlorine substitution, 7-Chloro-2,5-bis(trifluoromethyl)-1H-benzo[d]imidazole is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 288.58 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).
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), 7-Chloro-2,5-bis(trifluoromethyl)-1H-benzo[d]imidazole 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.
