Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
2,5-Dibromo-1,3-dichlorobenzene (CAS 19393-97-6) is a high-purity analytical reference standard with the molecular formula C6H2Br2Cl2 and a molecular weight of 304.79 g/mol.
2,5-Dibromo-1,3-dichlorobenzene (C6H2Br2Cl2) contains chlorine/bromine 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
CATO manufactures 2,5-Dibromo-1,3-dichlorobenzene 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.
