Chemical Structure
Description
The occurrence of 2-(Dimethylphosphinyl)phenol is closely related to organophosphorus functionality, a carboxylic acid group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
2-(Dimethylphosphinyl)phenol (CAS 1333230-31-1), molecular formula C8H11O2P and molecular weight 170.15 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to organophosphorus functionality, a carboxylic acid group, a hydroxyl group, an ether linkage, 2-(Dimethylphosphinyl)phenol is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 170.15 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
