Chemical Structure
Description
2,3-Dibromo-5-iodotoluene (CAS 1263377-39-4), molecular formula C7H5Br2I and molecular weight 375.83 g/mol, is a CATO reference standard with documented purity and traceability.
2,3-Dibromo-5-iodotoluene (C7H5Br2I) contains 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. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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-Dibromo-5-iodotoluene 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.
