Chemical Structure
Description
CATO supplies 2-(Trifluoromethyl)benzo[d]thiazole-6-carbonyl chloride (CAS 55439-74-2), a certified reference material (molecular formula C9H3ClF3NOS, MW 265.64 g/mol) for analytical method development and quality control.
Structurally, 2-(Trifluoromethyl)benzo[d]thiazole-6-carbonyl chloride (C9H3ClF3NOS) contains a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 7.0, corresponding to approximately 7 ring(s) or double-bond equivalent(s). With a molecular weight of 265.64 g/mol, it falls into the medium-molecular-weight range. 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.
As a certified reference material (CRM), 2-(Trifluoromethyl)benzo[d]thiazole-6-carbonyl chloride 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.
