1-Oxo-1-phenyl-1phosphinan-4-one CAS 38707-15-2

Description

The occurrence of 1-Oxo-1-phenyl-1phosphinan-4-one is closely related to organophosphorus functionality, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

1-Oxo-1-phenyl-1phosphinan-4-one (CAS 38707-15-2), molecular formula C11H13O2P and molecular weight 208.19 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, an aromatic ring system, 1-Oxo-1-phenyl-1phosphinan-4-one is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 208.19 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).

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
