Description
As a certified reference material (CRM), 1,4-Difluoro-2-(1-(phenylsulfonyl)cyclohexyl)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.
1,4-Difluoro-2-(1-(phenylsulfonyl)cyclohexyl)benzene (CAS 471903-54-5), molecular formula C18H18F2O2S and molecular weight 336.40 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a steroid core, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution, 1,4-Difluoro-2-(1-(phenylsulfonyl)cyclohexyl)benzene is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 336.40 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.
