Chemical Structure
Description
The molecular framework of (2e)-3-[1-benzyl-3-(pyridin-3-yl)-1h-pyrazol-4-yl]prop-2-enoic acid (C18H15N3O2) is characterized by a steroid core, an amide 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.
CATO supplies (2e)-3-[1-benzyl-3-(pyridin-3-yl)-1h-pyrazol-4-yl]prop-2-enoic acid (CAS 956244-24-9), a certified reference material (molecular formula C18H15N3O2, MW 305.33 g/mol) for analytical method development and quality control.
