Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 312.00 g/mol gives 5,6-Dibromo-1,2-dihydroacenaphthylene distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
5,6-Dibromo-1,2-dihydroacenaphthylene (CAS 14209-08-6), molecular formula C12H8Br2 and molecular weight 312.00 g/mol, is a CATO reference standard with documented purity and traceability.
5,6-Dibromo-1,2-dihydroacenaphthylene (C12H8Br2) contains bromine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
