Description
As a certified reference material (CRM), 4-((4-Methylbenzyl)oxy)benzofuran-6-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.
4-((4-Methylbenzyl)oxy)benzofuran-6-carboxylic acid (CAS 1291493-64-5), molecular formula C17H14O4 and molecular weight 282.29 g/mol, is a CATO reference standard with documented purity and traceability.
4-((4-Methylbenzyl)oxy)benzofuran-6-carboxylic acid (C17H14O4) contains a flavonoid core, a hydroxyl group, an ether linkage. 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.
