Description
CATO manufactures 7-Bromo-3-phenylbenzofuran 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.
7-Bromo-3-phenylbenzofuran (CAS 42434-89-9), molecular formula C14H9BrO and molecular weight 273.12 g/mol, is a CATO reference standard with documented purity and traceability.
7-Bromo-3-phenylbenzofuran (C14H9BrO) contains a hydroxyl group, an ether linkage, 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
