Chemical Structure

2-Bromo-5-ethoxy-1,3-dimethylbenzene CAS 91799-52-9 chemical structure

Description

The occurrence of 2-Bromo-5-ethoxy-1,3-dimethylbenzene is closely related to a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 2-Bromo-5-ethoxy-1,3-dimethylbenzene (CAS 91799-52-9), a certified reference material (molecular formula C10H13BrO, MW 229.11 g/mol) for analytical method development and quality control.

Owing to a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system, 2-Bromo-5-ethoxy-1,3-dimethylbenzene is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 229.11 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.
