Description
As a certified reference material (CRM), 4-Butoxy-2,3-difluorophenol 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.
CATO supplies 4-Butoxy-2,3-difluorophenol (CAS 136239-68-4), a certified reference material (molecular formula C10H12F2O2, MW 202.20 g/mol) for analytical method development and quality control.
4-Butoxy-2,3-difluorophenol (C10H12F2O2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, 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.
