Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3-(Triphenyl-l5-phosphanylidene)dihydrofuran-2(3H)-one.
CATO supplies 3-(Triphenyl-l5-phosphanylidene)dihydrofuran-2(3H)-one (CAS 34932-07-5), a certified reference material (molecular formula C22H19O2P, MW 346.36 g/mol) for analytical method development and quality control.
The molecular framework of 3-(Triphenyl-l5-phosphanylidene)dihydrofuran-2(3H)-one (C22H19O2P) 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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-(Triphenyl-l5-phosphanylidene)dihydrofuran-2(3H)-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.
