Chemical Structure
Description
1-tert-Butyl -5-(trifluoromethyl)-1H-imidazole (CAS 234450-32-9), molecular formula C8H11F3N2 and molecular weight 192.18 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrile group, fluorine substitution, 1-tert-Butyl -5-(trifluoromethyl)-1H-imidazole is typically white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 192.18 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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), 1-tert-Butyl -5-(trifluoromethyl)-1H-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.
