Chemical Structure

(E)-4-Phenyl-1-(triphenylphosphoranylidene)but-3-en-2-one CAS 98749-52-1 chemical structure

Description

CATO supplies (E)-4-Phenyl-1-(triphenylphosphoranylidene)but-3-en-2-one (CAS 98749-52-1), a certified reference material (molecular formula C28H23OP, MW 406.46 g/mol) for analytical method development and quality control.

(E)-4-Phenyl-1-(triphenylphosphoranylidene)but-3-en-2-one (C28H23OP) contains a steroid core, organophosphorus functionality, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
