Chemical Structure
Description
CATO supplies 1,3-Dibromo-5-iodobenzene (CAS 19752-57-9), a certified reference material (molecular formula C6H3Br2I, MW 361.80 g/mol) for analytical method development and quality control.
1,3-Dibromo-5-iodobenzene (C6H3Br2I) 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
