Chemical Structure
Description
CATO supplies 1-(Naphthalen-2-yl)-2-(triphenylphosphoranylidene)ethanone (CAS 1777-59-9), a certified reference material (molecular formula C30H23OP, MW 430.48 g/mol) for analytical method development and quality control.
Structurally, 1-(Naphthalen-2-yl)-2-(triphenylphosphoranylidene)ethanone (C30H23OP) contains a steroid core, organophosphorus functionality, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 19.5, corresponding to approximately 19 ring(s) or double-bond equivalent(s). With a molecular weight of 430.48 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), 1-(Naphthalen-2-yl)-2-(triphenylphosphoranylidene)ethanone 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.
