Chemical Structure
Description
The occurrence of 1-(9H-Fluoren-2-yl)-2-(triphenylphosphoranylidene)ethanone is closely related to organophosphorus functionality, a hydroxyl group, an ether linkage, a polycyclic aromatic system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 1-(9H-Fluoren-2-yl)-2-(triphenylphosphoranylidene)ethanone (CAS 88092-98-2), a certified reference material (molecular formula C33H25OP, MW 468.52 g/mol) for analytical method development and quality control.
The molecular framework of 1-(9H-Fluoren-2-yl)-2-(triphenylphosphoranylidene)ethanone (C33H25OP) is characterized by organophosphorus functionality, a hydroxyl group, an ether linkage, a polycyclic aromatic system. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
