Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 235.12 g/mol gives 2-(1-Bromoethyl)naphthalene distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 2-(1-Bromoethyl)naphthalene (CAS 52428-02-1), a certified reference material (molecular formula C12H11Br, MW 235.12 g/mol) for analytical method development and quality control.
2-(1-Bromoethyl)naphthalene (C12H11Br) 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
