Chemical Structure
Description
The occurrence of Ethyl 3-oxo-4-(triphenylphosphoranylidene)butanoate is closely related to a steroid core, a phosphonate group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Ethyl 3-oxo-4-(triphenylphosphoranylidene)butanoate (CAS 13148-05-5) is a high-purity analytical reference standard with the molecular formula C24H23O3P and a molecular weight of 390.41 g/mol.
The molecular framework of Ethyl 3-oxo-4-(triphenylphosphoranylidene)butanoate (C24H23O3P) is characterized by a steroid core, a phosphonate group, 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
