Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
1-Bromo-2,5-difluoro-4-iodobenzene (CAS 145349-66-2), molecular formula C6H2BrF2I and molecular weight 318.89 g/mol, is a CATO reference standard with documented purity and traceability.
1-Bromo-2,5-difluoro-4-iodobenzene (C6H2BrF2I) contains fluorine/bromine/iodine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point; 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.
CATO manufactures 1-Bromo-2,5-difluoro-4-iodobenzene 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.
