Chemical Structure
Description
2-Bromo-6-chloromethylnaphthalene, 97% (CAS 689290-84-4) is a high-purity analytical reference standard with the molecular formula C11H8BrCl and a molecular weight of 255.54 g/mol.
2-Bromo-6-chloromethylnaphthalene, 97% (C11H8BrCl) contains chlorine/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.
