Chemical Structure
Description
The molecular framework of (4aR,9aS)-4,4a,9,9a-Tetrahydroindeno[2,1-b][1,4]oxazin-3(2H)-one (C11H11NO2) is characterized by an amino-acid-derived structure, 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.
