Chemical Structure
Description
Owing to a steroid core, a hydroxyl group, an ether linkage, 1-(2-Chloroethyl)-2-methylbenzene is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 310.35 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-(2-Chloroethyl)-2-methylbenzene (CAS 39199-37-6), a certified reference material (molecular formula C22H14O2, MW 310.35 g/mol) for analytical method development and quality control.
