Chemical Structure
Description
CATO supplies ((Benzylsulfonyl)methyl)diphenylphosphine oxide (CAS 94548-77-3), a certified reference material (molecular formula C20H19O3PS, MW 370.40 g/mol) for analytical method development and quality control.
The molecular framework of ((Benzylsulfonyl)methyl)diphenylphosphine oxide (C20H19O3PS) is characterized by a steroid core, a sulfone group, a phosphonate group, 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 ((Benzylsulfonyl)methyl)diphenylphosphine 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.
