Chemical Structure
Description
The occurrence of [4-(Trifluoromethyl)phenyl](triphenylphosphine)gold is closely related to organophosphorus functionality, fluorine substitution, a polycyclic aromatic system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
[4-(Trifluoromethyl)phenyl](triphenylphosphine)gold (CAS 1130440-65-1), molecular formula C25H20AuF3P and molecular weight 605.36 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to organophosphorus functionality, fluorine substitution, a polycyclic aromatic system, [4-(Trifluoromethyl)phenyl](triphenylphosphine)gold is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 605.36 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), [4-(Trifluoromethyl)phenyl](triphenylphosphine)gold 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.
