Chemical Structure

1-Bromo-5-methoxy-2,4-dimethylbenzene CAS 77771-60-9 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 215.09 g/mol gives 1-Bromo-5-methoxy-2,4-dimethylbenzene distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 1-Bromo-5-methoxy-2,4-dimethylbenzene (CAS 77771-60-9), a certified reference material (molecular formula C9H11BrO, MW 215.09 g/mol) for analytical method development and quality control.

Owing to a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system, 1-Bromo-5-methoxy-2,4-dimethylbenzene is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 215.09 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.
