Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Tris(2-fluorophenyl)phosphine.
CATO supplies Tris(2-fluorophenyl)phosphine (CAS 84350-73-2), a certified reference material (molecular formula C18H12F3P, MW 316.26 g/mol) for analytical method development and quality control.
Owing to organophosphorus functionality, fluorine substitution, a polycyclic aromatic system, Tris(2-fluorophenyl)phosphine is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 316.26 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.
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(2-fluorophenyl)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.
