1-(tert-butyl)-4-(trichloromethyl)benzene (CAS 153357-88-1), molecular formula C11H13Cl3 and molecular weight 251.58 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to chlorine substitution, an aromatic ring system, 1-(tert-butyl)-4-(trichloromethyl)benzene is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 251.58 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).
As a certified reference material (CRM), 1-(tert-butyl)-4-(trichloromethyl)benzene 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.
