CATO supplies 483-66-9 Sphondin 2H-Furo(2,3-h)-1-benzopyran-2-one, 6-methoxy- 6-Methoxy-2H-furo(2,3-h)-1-benzopyran-2-one HSDB 8482 (CAS 483-66-9), a certified reference material (molecular formula C12H8O4, MW 216.19 g/mol) for analytical method development and quality control.
483-66-9 Sphondin 2H-Furo(2,3-h)-1-benzopyran-2-one, 6-methoxy- 6-Methoxy-2H-furo(2,3-h)-1-benzopyran-2-one HSDB 8482 (C12H8O4) 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).
CATO manufactures 483-66-9 Sphondin 2H-Furo(2,3-h)-1-benzopyran-2-one, 6-methoxy- 6-Methoxy-2H-furo(2,3-h)-1-benzopyran-2-one HSDB 8482 under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
