Chemical Structure
Description
The occurrence of N-(2-Cyano-2-(triphenylphosphoranylidene)ethanethioyl)benzamide is closely related to a steroid core, an amide group, sulfur-containing functionality, organophosphorus functionality, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
N-(2-Cyano-2-(triphenylphosphoranylidene)ethanethioyl)benzamide (CAS 155786-93-9) is a high-purity analytical reference standard with the molecular formula C28H21N2OPS and a molecular weight of 464.52 g/mol.
The molecular framework of N-(2-Cyano-2-(triphenylphosphoranylidene)ethanethioyl)benzamide (C28H21N2OPS) 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. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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), N-(2-Cyano-2-(triphenylphosphoranylidene)ethanethioyl)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.
