Chemical Structure

Bis(3,5-di(9H-fluoren-9-yl)phenyl)diphenylmethane CAS 944465-42-3 chemical structure

Description

The occurrence of Bis(3,5-di(9H-fluoren-9-yl)phenyl)diphenylmethane is closely related to a polycyclic aromatic system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies Bis(3,5-di(9H-fluoren-9-yl)phenyl)diphenylmethane (CAS 944465-42-3), a certified reference material (molecular formula C77H52, MW 977.24 g/mol) for analytical method development and quality control.

Owing to a polycyclic aromatic system, Bis(3,5-di(9H-fluoren-9-yl)phenyl)diphenylmethane is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 977.24 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).

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.
