Chemical Structure

2-Fluoro-9-fluorenone-9- CAS 334973-78-3 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 2-Fluoro-9-fluorenone-9-.

CATO supplies 2-Fluoro-9-fluorenone-9- (CAS 334973-78-3), a certified reference material (molecular formula C12[13C]H7FO, MW 199.19 g/mol) for analytical method development and quality control.

The molecular framework of 2-Fluoro-9-fluorenone-9- (C12[13C]H7FO) is characterized by a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring 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).

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.
