Chemical Structure
Description
The occurrence of (4Z)-1,3-Diphenyl-4-{[2-(prop-2-en-1-yloxy)naphthalen-1-yl]methylidene}-4,5-dihydro-1H-pyrazol-5-one 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.
(4Z)-1,3-Diphenyl-4-{[2-(prop-2-en-1-yloxy)naphthalen-1-yl]methylidene}-4,5-dihydro-1H-pyrazol-5-one (CAS 321432-15-9), molecular formula C29H22N2O2 and molecular weight 430.50 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of (4Z)-1,3-Diphenyl-4-{[2-(prop-2-en-1-yloxy)naphthalen-1-yl]methylidene}-4,5-dihydro-1H-pyrazol-5-one (C29H22N2O2) 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 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
