Compared with other compounds in its class, the molecular weight of 550.29 g/mol gives Tris(pentafluorophenyl)phosphine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Tris(pentafluorophenyl)phosphine (CAS 1259-35-4), a certified reference material (molecular formula C18H18F15P, MW 550.29 g/mol) for analytical method development and quality control.
Owing to organophosphorus functionality, fluorine substitution, Tris(pentafluorophenyl)phosphine is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 550.29 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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(pentafluorophenyl)phosphine 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.
