Owing to a sulfone group, a phosphonate group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, Prothiophos-Oxon is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 329.18 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).
Prothiophos-Oxon (CAS 38527-91-2), molecular formula C11H15Cl2O3PS and molecular weight 329.18 g/mol, is a CATO reference standard with documented purity and traceability.
