Chemical Structure
Description
The occurrence of 1-(4-Benzoylphenyl)-1h-pyrrole-2,5-dione is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
1-(4-Benzoylphenyl)-1h-pyrrole-2,5-dione (CAS 92944-71-3) is a high-purity analytical reference standard with the molecular formula C17H11NO3 and a molecular weight of 277.27 g/mol.
The molecular framework of 1-(4-Benzoylphenyl)-1h-pyrrole-2,5-dione (C17H11NO3) is characterized by a steroid core, an amide 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.
