CATO supplies 1-Ethoxy-2,3-difluoro-4-((4-(4-propylcyclohexyl)phenyl)ethynyl)benzene (CAS 123560-57-6), a certified reference material (molecular formula C25H28F2O, MW 382.49 g/mol) for analytical method development and quality control.
The molecular framework of 1-Ethoxy-2,3-difluoro-4-((4-(4-propylcyclohexyl)phenyl)ethynyl)benzene (C25H28F2O) is characterized by a steroid core, a hydroxyl group, an ether linkage, fluorine substitution. 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.
