Chemical Structure

4-Amino-5-(difluoromethyl)-3-hydroxypicolinic acid CAS 1805082-80-7 chemical structure

Description

The occurrence of 4-Amino-5-(difluoromethyl)-3-hydroxypicolinic acid is closely related to an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

4-Amino-5-(difluoromethyl)-3-hydroxypicolinic acid (CAS 1805082-80-7) is a high-purity analytical reference standard with the molecular formula C7H6F2N2O3 and a molecular weight of 204.13 g/mol.

4-Amino-5-(difluoromethyl)-3-hydroxypicolinic acid (C7H6F2N2O3) 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.

As a certified reference material (CRM), 4-Amino-5-(difluoromethyl)-3-hydroxypicolinic acid meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
