The molecular framework of Bis(4-fluorophenyl)chlorophosphine (C12H8ClF2P) is characterized by organophosphorus functionality, fluorine/chlorine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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).
Bis(4-fluorophenyl)chlorophosphine (CAS 23039-97-6) is a high-purity analytical reference standard with the molecular formula C12H8ClF2P and a molecular weight of 256.62 g/mol.
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), Bis(4-fluorophenyl)chlorophosphine 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.
