Chemical Structure

Dioxabenzofos CAS 3811-49-2 chemical structure

Description

Owing to a sulfone group, a phosphonate group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system, Dioxabenzofos is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 216.19 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 Dioxabenzofos (CAS 3811-49-2), a certified reference material (molecular formula C8H9O3PS, MW 216.19 g/mol) for analytical method development and quality control.
