Description
CATO manufactures 9-Bromo-7,7-dimethyl-7H-benzo[c]fluorene 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.
9-Bromo-7,7-dimethyl-7H-benzo[c]fluorene (CAS 1198396-46-1) is a high-purity analytical reference standard with the molecular formula C19H15Br and a molecular weight of 323.23 g/mol.
9-Bromo-7,7-dimethyl-7H-benzo[c]fluorene (C19H15Br) contains bromine substitution, a polycyclic aromatic system. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; 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.
