Chemical Structure

2-Bromo-9,9'-bifluorenylidene CAS 102289-35-0 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-Bromo-9,9'-bifluorenylidene.

CATO supplies 2-Bromo-9,9'-bifluorenylidene (CAS 102289-35-0), a certified reference material (molecular formula C26H15Br, MW 407.30 g/mol) for analytical method development and quality control.

The molecular framework of 2-Bromo-9,9'-bifluorenylidene (C26H15Br) is characterized by bromine substitution, 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 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.
