(Z)-5-((3-(4-Isobutoxyphenyl)-1-phenyl-1H-pyrazol-4-yl)methylene)-2-phenylthiazolo[3,2-b][1,2,4]triazol-6(5H)-one CAS 956759-61-8

Description

The molecular framework of (Z)-5-((3-(4-Isobutoxyphenyl)-1-phenyl-1H-pyrazol-4-yl)methylene)-2-phenylthiazolo[3,2-b][1,2,4]triazol-6(5H)-one (C30H25N5O2S) 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 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.
