Chemical Structure
Description
The molecular framework of 5-(4-Fluorophenyl)-7-(perfluoroethyl)-4,5,6,7-tetrahydropyrazolo[1,5-a]pyrimidine-2-carbohydrazide (C15H13F6N5O) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine 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.
5-(4-Fluorophenyl)-7-(perfluoroethyl)-4,5,6,7-tetrahydropyrazolo[1,5-a]pyrimidine-2-carbohydrazide (CAS 832739-62-5), molecular formula C15H13F6N5O and molecular weight 393.29 g/mol, is a CATO reference standard with documented purity and traceability.
