Chemical Structure

4-(Difluoromethyl)-3-(hydroxymethyl)-5-methylpyridin-2-ol CAS 1804867-75-1 chemical structure

Description

As a certified reference material (CRM), 4-(Difluoromethyl)-3-(hydroxymethyl)-5-methylpyridin-2-ol 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.

4-(Difluoromethyl)-3-(hydroxymethyl)-5-methylpyridin-2-ol (CAS 1804867-75-1) is a high-purity analytical reference standard with the molecular formula C8H9F2NO2 and a molecular weight of 189.16 g/mol.

4-(Difluoromethyl)-3-(hydroxymethyl)-5-methylpyridin-2-ol (C8H9F2NO2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. 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.
