2-Methoxy-4-(2-bromoethyl)anisole 3,4-Dimethoxy-1-(2-bromoethyl)benzene 3,4-Dimethoxyphenethyl bromide 40173-90-8 (CAS 40173-90-8), molecular formula C10H19BrO2 and molecular weight 251.16 g/mol, is a CATO reference standard with documented purity and traceability.
2-Methoxy-4-(2-bromoethyl)anisole 3,4-Dimethoxy-1-(2-bromoethyl)benzene 3,4-Dimethoxyphenethyl bromide 40173-90-8 (C10H19BrO2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; 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.
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.
