2-Hydroxy-5,5-dimethyl-4-phenyl-1,3,2-dioxaphosphinane 2-oxide CAS 98634-22-1

Description

Owing to a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system, 2-Hydroxy-5,5-dimethyl-4-phenyl-1,3,2-dioxaphosphinane 2-oxide is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 242.21 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

2-Hydroxy-5,5-dimethyl-4-phenyl-1,3,2-dioxaphosphinane 2-oxide (CAS 98634-22-1) is a high-purity analytical reference standard with the molecular formula C11H15O4P and a molecular weight of 242.21 g/mol.

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.
