Chemical Structure

1,3-Dimethyl-2-(prop-2-yn-1-yl)benzene CAS 73234-91-0 chemical structure

Description

Owing to an aromatic ring system, 1,3-Dimethyl-2-(prop-2-yn-1-yl)benzene is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 144.21 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).

CATO supplies 1,3-Dimethyl-2-(prop-2-yn-1-yl)benzene (CAS 73234-91-0), a certified reference material (molecular formula C11H12, MW 144.21 g/mol) for analytical method development and quality control.

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.
