(2-fluorophenyl)(trifluoromethyl)sulfane (CAS 1978-16-1), molecular formula C7H4F4S and molecular weight 196.17 g/mol, is a CATO reference standard with documented purity and traceability.
(2-fluorophenyl)(trifluoromethyl)sulfane (C7H4F4S) contains sulfur-containing functionality, fluorine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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-fluorophenyl)(trifluoromethyl)sulfane 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.
