1-Bromo-4-((2-methoxyethyl)sulfonyl)butane (CAS 1153353-75-3), molecular formula C7H15BrO3S and molecular weight 259.16 g/mol, is a CATO reference standard with documented purity and traceability.
1-Bromo-4-((2-methoxyethyl)sulfonyl)butane (C7H15BrO3S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, 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.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
