Chemical Structure
Description
The occurrence of (2S,2'S,3S,3'S)-WingPhos is closely related to organophosphorus functionality, a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies (2S,2'S,3S,3'S)-WingPhos (CAS 1435940-19-4), a certified reference material (molecular formula C50H44O2P2, MW 738.83 g/mol) for analytical method development and quality control.
The molecular framework of (2S,2'S,3S,3'S)-WingPhos (C50H44O2P2) is characterized by organophosphorus functionality, a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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 (2S,2'S,3S,3'S)-WingPhos 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.
