Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2,3,5-Tribromo-1,4-dihydroxyanthracene-9,10-dione.
2,3,5-Tribromo-1,4-dihydroxyanthracene-9,10-dione (CAS 106200-76-4) is a high-purity analytical reference standard with the molecular formula C14H5Br3O4 and a molecular weight of 476.90 g/mol.
2,3,5-Tribromo-1,4-dihydroxyanthracene-9,10-dione (C14H5Br3O4) contains a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, a polycyclic aromatic system. It is notably hygroscopic, 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures 2,3,5-Tribromo-1,4-dihydroxyanthracene-9,10-dione 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.
