Chemical Structure
Description
The molecular framework of 5-[(4-Methoxyphenyl)sulfanyl]-1-methyl-3-phenyl-1H-pyrazole-4-carbaldehyde (C18H16N2O2S) is characterized by a steroid core, an amide group, a sulfone 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.
