Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 255.54 g/mol gives 2-(Bromomethyl)-3-chloronaphthalene distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
2-(Bromomethyl)-3-chloronaphthalene (CAS 99867-10-4), molecular formula C11H8BrCl and molecular weight 255.54 g/mol, is a CATO reference standard with documented purity and traceability.
2-(Bromomethyl)-3-chloronaphthalene (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.
