Chemical Structure
Description
1-(3-Fluoro-4-methoxybenzyl)-1H-pyrazol-4-amine (C11H12FN3O) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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).
1-(3-Fluoro-4-methoxybenzyl)-1H-pyrazol-4-amine (CAS 1152582-97-2), molecular formula C11H12FN3O and molecular weight 221.23 g/mol, is a CATO reference standard with documented purity and traceability.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
