Chemical Structure

2-(9,9-Diphenyl-9H-fluoren-4-yl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane CAS 1259280-37-9 chemical structure

Description

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system, 2-(9,9-Diphenyl-9H-fluoren-4-yl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 444.37 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).

CATO supplies 2-(9,9-Diphenyl-9H-fluoren-4-yl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane (CAS 1259280-37-9), a certified reference material (molecular formula C31H29BO2, MW 444.37 g/mol) for analytical method development and quality control.

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.
