Chemical Structure
Description
The occurrence of 5-(4-Fluorophenyl)-1-methyl-1H-pyrazol-3-yl trifluoromethanesulfonate is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
5-(4-Fluorophenyl)-1-methyl-1H-pyrazol-3-yl trifluoromethanesulfonate (CAS 623577-34-4) is a high-purity analytical reference standard with the molecular formula C11H8F4N2O3S and a molecular weight of 324.25 g/mol.
The molecular framework of 5-(4-Fluorophenyl)-1-methyl-1H-pyrazol-3-yl trifluoromethanesulfonate (C11H8F4N2O3S) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone 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 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).
