Chemical Structure

Ethyl 5-methyl-7-(perfluoroethyl)-4,5,6,7-tetrahydropyrazolo[1,5-a]pyrimidine-2-carboxylate CAS 725699-01-4 chemical structure

Description

The molecular framework of Ethyl 5-methyl-7-(perfluoroethyl)-4,5,6,7-tetrahydropyrazolo[1,5-a]pyrimidine-2-carboxylate (C12H14F5N3O2) 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
