Chemical Structure
Description
The molecular framework of 1-((1-Cyclopentyl-4,5,6,7-tetrahydro-1H-indazol-3-yl)methyl)-3-(thiophen-2-yl)urea (C18H24N4OS) is characterized by a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
