4-Amino-2-(difluoromethyl)-5-(hydroxymethyl)pyridin-3-ol (CAS 1805331-69-4), molecular formula C7H8F2N2O2 and molecular weight 190.15 g/mol, is a CATO reference standard with documented purity and traceability.
4-Amino-2-(difluoromethyl)-5-(hydroxymethyl)pyridin-3-ol (C7H8F2N2O2) 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
