Chemical Structure
Description
The occurrence of Tris(3-fluorophenyl)phosphine is closely related to organophosphorus functionality, fluorine substitution, a polycyclic aromatic system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies Tris(3-fluorophenyl)phosphine (CAS 23039-94-3), a certified reference material (molecular formula C18H12F3P, MW 316.26 g/mol) for analytical method development and quality control.
Structurally, Tris(3-fluorophenyl)phosphine (C18H12F3P) contains organophosphorus functionality, fluorine substitution, a polycyclic aromatic system. 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 316.26 g/mol, it falls into the moderately-high-molecular-weight range. 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(3-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.
