Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (4-Hydroxyphenyl)dimethylphosphine oxide.
(4-Hydroxyphenyl)dimethylphosphine oxide (CAS 27947-41-7) is a high-purity analytical reference standard with the molecular formula C8H11O2P and a molecular weight of 170.15 g/mol.
Structurally, (4-Hydroxyphenyl)dimethylphosphine oxide (C8H11O2P) contains organophosphorus functionality, a carboxylic acid group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 3.5, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 170.15 g/mol, it falls into the medium-molecular-weight range. 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.
