4-(4-Methoxyphenoxy)butane-1-sulfonyl chloride (CAS 1342027-90-0), molecular formula C11H15ClO4S and molecular weight 278.75 g/mol, is a CATO reference standard with documented purity and traceability.

4-(4-Methoxyphenoxy)butane-1-sulfonyl chloride (C11H15ClO4S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. It is notably hygroscopic, 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
