Chemical Structure
Description
The molecular framework of 4-Bromo-1-cyclopentyl-5-(propoxymethyl)-1H-pyrazole (C12H19BrN2O) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, bromine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), 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-Bromo-1-cyclopentyl-5-(propoxymethyl)-1H-pyrazole (CAS 1856048-08-2) is a high-purity analytical reference standard with the molecular formula C12H19BrN2O and a molecular weight of 287.20 g/mol.
