5-Chloro-2-(trifluoromethyl)-1H-benzo[d]imidazole (CAS 656-49-5), molecular formula C8H4ClF3N2 and molecular weight 220.58 g/mol, is a CATO reference standard with documented purity and traceability.
5-Chloro-2-(trifluoromethyl)-1H-benzo[d]imidazole (C8H4ClF3N2) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine/chlorine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
CATO manufactures 5-Chloro-2-(trifluoromethyl)-1H-benzo[d]imidazole 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.
