Chemical Structure
Description
The molecular framework of (S)-2-(2-(Diphenylphosphino)phenyl)-4-isobutyl-4,5-dihydrooxazole (C25H26NOP) is characterized by a steroid core, an amide group, 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.
CATO supplies (S)-2-(2-(Diphenylphosphino)phenyl)-4-isobutyl-4,5-dihydrooxazole (CAS 2757082-85-0), a certified reference material (molecular formula C25H26NOP, MW 387.45 g/mol) for analytical method development and quality control.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
