Chemical Structure
Description
2-(Benzyloxy)-5-bromo-1-chloro-3-fluorobenzene (CAS 1881293-72-6), molecular formula C13H9BrClFO and molecular weight 315.57 g/mol, is a CATO reference standard with documented purity and traceability.
2-(Benzyloxy)-5-bromo-1-chloro-3-fluorobenzene (C13H9BrClFO) contains a hydroxyl group, an ether linkage, fluorine/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.
