((2-Hydroxycyclohexyl)methyl)diphenylphosphine oxide CAS 89358-53-2

Description

The occurrence of ((2-Hydroxycyclohexyl)methyl)diphenylphosphine oxide is closely related to a steroid core, organophosphorus functionality, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

((2-Hydroxycyclohexyl)methyl)diphenylphosphine oxide (CAS 89358-53-2) is a high-purity analytical reference standard with the molecular formula C19H23O2P and a molecular weight of 314.36 g/mol.

Owing to a steroid core, organophosphorus functionality, a hydroxyl group, an ether linkage, ((2-Hydroxycyclohexyl)methyl)diphenylphosphine oxide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 314.36 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
