Chemical Structure

Pentabromobenzylchloride CAS 58495-09-3 chemical structure

Description

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.

CATO supplies Pentabromobenzylchloride (CAS 58495-09-3), a certified reference material (molecular formula C7H2Br5Cl, MW 521.06 g/mol) for analytical method development and quality control.

Owing to chlorine/bromine substitution, an aromatic ring system, Pentabromobenzylchloride is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 521.06 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.
