Chemical Structure

4-Amino-6-(difluoromethyl)pyridine-2,3-diol CAS 1805244-10-3 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 176.12 g/mol gives 4-Amino-6-(difluoromethyl)pyridine-2,3-diol distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 4-Amino-6-(difluoromethyl)pyridine-2,3-diol (CAS 1805244-10-3), a certified reference material (molecular formula C6H6F2N2O2, MW 176.12 g/mol) for analytical method development and quality control.

4-Amino-6-(difluoromethyl)pyridine-2,3-diol (C6H6F2N2O2) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine 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.
