Chemical Structure
Description
6,8-Dibromo-3-((4-chlorophenyl)sulfonyl)-2h-chromen-2-one (CAS 775315-37-2), molecular formula C15H7Br2ClO4S and molecular weight 478.54 g/mol, is a CATO reference standard with documented purity and traceability.
6,8-Dibromo-3-((4-chlorophenyl)sulfonyl)-2h-chromen-2-one (C15H7Br2ClO4S) contains a flavonoid core, a sulfone group, a hydroxyl group, an ether linkage, chlorine/bromine substitution. 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).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
CATO manufactures 6,8-Dibromo-3-((4-chlorophenyl)sulfonyl)-2h-chromen-2-one 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.
