Chemical Structure
Description
The molecular framework of 3-[(2-Chlorophenyl)methyl]-4-imino-6,7-dimethoxy-1,2,3,4-tetrahydroquinazoline-2-thione (C17H16ClN3O2S) is characterized by a steroid core, an amide group, a sulfone 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.
