Bis(2-naphthyl)phosphine oxide CAS 78871-05-3

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Bis(2-naphthyl)phosphine oxide.

CATO supplies Bis(2-naphthyl)phosphine oxide (CAS 78871-05-3), a certified reference material (molecular formula C20H15OP, MW 302.31 g/mol) for analytical method development and quality control.

Owing to a steroid core, organophosphorus functionality, a hydroxyl group, an ether linkage, Bis(2-naphthyl)phosphine oxide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 302.31 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.

CATO manufactures Bis(2-naphthyl)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.
