Chemical Structure
Description
The molecular framework of 4-[5-(Furan-2-yl)-1H-pyrazol-3-yl]-1-[(4-nitrophenyl)methyl]piperidine (C19H20N4O3) 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. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
4-[5-(Furan-2-yl)-1H-pyrazol-3-yl]-1-[(4-nitrophenyl)methyl]piperidine (CAS 321848-26-4), molecular formula C19H20N4O3 and molecular weight 352.39 g/mol, is a CATO reference standard with documented purity and traceability.
