Chemical Structure
Description
The occurrence of 3,3-Dimethyl-1-(triphenylphosphoranylidene)butan-2-one is closely related to a steroid core, organophosphorus functionality, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
3,3-Dimethyl-1-(triphenylphosphoranylidene)butan-2-one (CAS 26487-93-4) is a high-purity analytical reference standard with the molecular formula C24H25OP and a molecular weight of 360.43 g/mol.
The molecular framework of 3,3-Dimethyl-1-(triphenylphosphoranylidene)butan-2-one (C24H25OP) is characterized by a steroid core, 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), 3,3-Dimethyl-1-(triphenylphosphoranylidene)butan-2-one 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.
