Chemical Structure

4,5-Dichloro-2-(difluoromethyl)-3-nitropyridine CAS 1804702-38-2 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 243.00 g/mol gives 4,5-Dichloro-2-(difluoromethyl)-3-nitropyridine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

4,5-Dichloro-2-(difluoromethyl)-3-nitropyridine (CAS 1804702-38-2), molecular formula C6H2Cl2F2N2O2 and molecular weight 243.00 g/mol, is a CATO reference standard with documented purity and traceability.

4,5-Dichloro-2-(difluoromethyl)-3-nitropyridine (C6H2Cl2F2N2O2) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, an aromatic ring system. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; 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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
