Chemical Structure
Description
1-Benzyl-3-bromo-5-fluorobenzene (CAS 875783-04-3) is a high-purity analytical reference standard with the molecular formula C13H10BrF and a molecular weight of 265.12 g/mol.
1-Benzyl-3-bromo-5-fluorobenzene (C13H10BrF) contains fluorine/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.
