Chemical Structure
Description
6-Bromoimidazo[1,2-b]pyridazine (C6H4BrN3) contains a nitrile group, 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).
6-Bromoimidazo[1,2-b]pyridazine (CAS 1159977-65-7), molecular formula C6H4BrN3 and molecular weight 198.02 g/mol, is a CATO reference standard with documented purity and traceability.
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.
