Chemical Structure
Description
Owing to chlorine/bromine substitution, an aromatic ring system, 4-Bromo-1-(tert-butyl)-2-chlorobenzene is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 247.56 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).
4-Bromo-1-(tert-butyl)-2-chlorobenzene (CAS 477720-72-2) is a high-purity analytical reference standard with the molecular formula C10H12BrCl and a molecular weight of 247.56 g/mol.
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.
