Compared with other compounds in its class, the molecular weight of 307.16 g/mol gives Methyl 3-(4-bromobenzenesulfonyl)propanoate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Methyl 3-(4-bromobenzenesulfonyl)propanoate (CAS 14223-24-6), molecular formula C10H11BrO4S and molecular weight 307.16 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system, Methyl 3-(4-bromobenzenesulfonyl)propanoate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 307.16 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
