Methyl(phenyl)phosphine oxide CAS 19315-13-0 chemical structure

Description

CATO manufactures Methyl(phenyl)phosphine oxide under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.

CATO supplies Methyl(phenyl)phosphine oxide (CAS 19315-13-0), a certified reference material (molecular formula C7H9OP, MW 140.12 g/mol) for analytical method development and quality control.

Owing to organophosphorus functionality, a hydroxyl group, an ether linkage, Methyl(phenyl)phosphine oxide is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 140.12 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.
