Chemical Structure

Phenylarsonic Acid CAS 98-05-5 chemical structure

Description

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, Phenylarsonic Acid is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 202.04 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 Phenylarsonic Acid (CAS 98-05-5), a certified reference material (molecular formula C6H7AsO3, MW 202.04 g/mol) for analytical method development and quality control.
