Chemical Structure
Description
The occurrence of Tris(perfluorophenyl)phosphine oxide is closely related to a steroid core, organophosphorus functionality, a hydroxyl group, an ether linkage, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Tris(perfluorophenyl)phosphine oxide (CAS 2729-11-5) is a high-purity analytical reference standard with the molecular formula C18F15OP and a molecular weight of 548.14 g/mol.
Structurally, Tris(perfluorophenyl)phosphine oxide (C18F15OP) contains a steroid core, organophosphorus functionality, a hydroxyl group, an ether linkage, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 11.5, corresponding to approximately 11 ring(s) or double-bond equivalent(s). With a molecular weight of 548.14 g/mol, it falls into the moderately-high-molecular-weight range. 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), Tris(perfluorophenyl)phosphine oxide 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.
