Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
Bis(pentafluorophenyl)phenylphosphine (CAS 5074-71-5), molecular formula C18H5F10P and molecular weight 442.19 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to organophosphorus functionality, fluorine substitution, a polycyclic aromatic system, Bis(pentafluorophenyl)phenylphosphine is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 442.19 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
As a certified reference material (CRM), Bis(pentafluorophenyl)phenylphosphine 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.
