Description
As a certified reference material (CRM), 6-Methoxy-4-methyl-1-benzofuran-2-carboxylic 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.
CATO supplies 6-Methoxy-4-methyl-1-benzofuran-2-carboxylic acid (CAS 1427427-80-2), a certified reference material (molecular formula C11H10O4, MW 206.19 g/mol) for analytical method development and quality control.
6-Methoxy-4-methyl-1-benzofuran-2-carboxylic acid (C11H10O4) contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. It is notably hygroscopic, 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.
