Chemical Structure

6-Bromo-3-(p-tolyl)-2-(p-tolylethynyl)quinoxaline CAS 1319039-31-0 chemical structure

Description

Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, bromine substitution, 6-Bromo-3-(p-tolyl)-2-(p-tolylethynyl)quinoxaline is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 413.31 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).

6-Bromo-3-(p-tolyl)-2-(p-tolylethynyl)quinoxaline (CAS 1319039-31-0) is a high-purity analytical reference standard with the molecular formula C24H17BrN2 and a molecular weight of 413.31 g/mol.
