Chemical Structure
Description
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
CATO supplies (4-Fluorophenyl)diphenylphosphane (CAS 18437-72-4), a certified reference material (molecular formula C18H14FP, MW 280.28 g/mol) for analytical method development and quality control.
Owing to organophosphorus functionality, fluorine substitution, a polycyclic aromatic system, (4-Fluorophenyl)diphenylphosphane is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 280.28 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).
CATO manufactures (4-Fluorophenyl)diphenylphosphane under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
