Chemical Structure
Description
The occurrence of 4-Fluoro-3,5-dimethyl-1H-pyrazole is closely related to a nitrile group, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
4-Fluoro-3,5-dimethyl-1H-pyrazole (CAS 57160-76-6), molecular formula C5H7FN2 and molecular weight 114.12 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrile group, fluorine substitution, 4-Fluoro-3,5-dimethyl-1H-pyrazole is typically white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 114.12 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
