2-Bromo-4-ethynyl-1,3,5-trimethylbenzene CAS 5471-85-2

Description

Compared with other compounds in its class, the molecular weight of 223.11 g/mol gives 2-Bromo-4-ethynyl-1,3,5-trimethylbenzene distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

2-Bromo-4-ethynyl-1,3,5-trimethylbenzene (CAS 5471-85-2) is a high-purity analytical reference standard with the molecular formula C11H11Br and a molecular weight of 223.11 g/mol.

Owing to bromine substitution, an aromatic ring system, 2-Bromo-4-ethynyl-1,3,5-trimethylbenzene is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 223.11 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).
