Compared with other compounds in its class, the molecular weight of 302.31 g/mol gives Bis(1-naphthyl)phosphine oxide distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Bis(1-naphthyl)phosphine oxide (CAS 13440-07-8), a certified reference material (molecular formula C20H15OP, MW 302.31 g/mol) for analytical method development and quality control.
The molecular framework of Bis(1-naphthyl)phosphine oxide (C20H15OP) is characterized by a steroid core, organophosphorus functionality, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures Bis(1-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.
