Chemical Structure
Description
Owing to sulfur-containing functionality, a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system, 1-(3-Bromophenyl)-2-(ethylthio)ethan-1-one is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 259.16 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.
1-(3-Bromophenyl)-2-(ethylthio)ethan-1-one (CAS 1157204-81-3), molecular formula C10H11BrOS and molecular weight 259.16 g/mol, is a CATO reference standard with documented purity and traceability.
