Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 453.54 g/mol gives 4-Methyl-N-(2-thioxo-1-(triphenylphosphoranylidene)ethyl)benzamide distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 4-Methyl-N-(2-thioxo-1-(triphenylphosphoranylidene)ethyl)benzamide (CAS 90283-68-4), a certified reference material (molecular formula C28H24NOPS, MW 453.54 g/mol) for analytical method development and quality control.
The molecular framework of 4-Methyl-N-(2-thioxo-1-(triphenylphosphoranylidene)ethyl)benzamide (C28H24NOPS) is characterized by a steroid core, an amide group, sulfur-containing functionality, 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
As a certified reference material (CRM), 4-Methyl-N-(2-thioxo-1-(triphenylphosphoranylidene)ethyl)benzamide meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
