Chemical Structure
Description
Owing to a nitrile group, fluorine/iodine substitution, an aromatic ring system, 1-(2,2-Difluoroethyl)-4-iodo-1H-pyrazole-3-carbonitrile is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 283.02 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).
1-(2,2-Difluoroethyl)-4-iodo-1H-pyrazole-3-carbonitrile (CAS 1354705-32-0), molecular formula C6H4F2IN3 and molecular weight 283.02 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.
