Chemical Structure

2-Chloro-5-(difluoromethoxy)isonicotinonitrile CAS 1806072-72-9 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 204.56 g/mol gives 2-Chloro-5-(difluoromethoxy)isonicotinonitrile distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

2-Chloro-5-(difluoromethoxy)isonicotinonitrile (CAS 1806072-72-9) is a high-purity analytical reference standard with the molecular formula C7H3ClF2N2O and a molecular weight of 204.56 g/mol.

2-Chloro-5-(difluoromethoxy)isonicotinonitrile (C7H3ClF2N2O) contains an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point; 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).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
