Chemical Structure
Description
The occurrence of 2-((Triphenylphosphoranylidene)amino)ethyl benzoate is closely related to a steroid core, an amide group, organophosphorus functionality, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
2-((Triphenylphosphoranylidene)amino)ethyl benzoate (CAS 179039-70-4), molecular formula C27H24NO2P and molecular weight 425.46 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 2-((Triphenylphosphoranylidene)amino)ethyl benzoate (C27H24NO2P) contains a steroid core, an amide group, organophosphorus functionality, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 16.5, corresponding to approximately 16 ring(s) or double-bond equivalent(s). With a molecular weight of 425.46 g/mol, it falls into the moderately-high-molecular-weight range. 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), 2-((Triphenylphosphoranylidene)amino)ethyl benzoate 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.
