Chemical Structure
Description
The molecular framework of 12-chloro-8-methyl-3-[(1r,4r)-4-(pyridin-2-yloxy)cyclohexyl]-2,4,5,8-tetraazatricyclo[8.4.0.0,tetradeca-1(10),3,5,11,13-pentaene 1228088-30-9 SB19643 (C22H24ClN5O) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. 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.
