N-(Triphenylphosphoranylidene)benzenesulfonamide CAS 1056-25-3

Description

Compared with other compounds in its class, the molecular weight of 417.46 g/mol gives N-(Triphenylphosphoranylidene)benzenesulfonamide distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

N-(Triphenylphosphoranylidene)benzenesulfonamide (CAS 1056-25-3) is a high-purity analytical reference standard with the molecular formula C24H20NO2PS and a molecular weight of 417.46 g/mol.

The molecular framework of N-(Triphenylphosphoranylidene)benzenesulfonamide (C24H20NO2PS) is characterized by a steroid core, an amide group, a sulfone group, 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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 N-(Triphenylphosphoranylidene)benzenesulfonamide 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.
