CATO supplies 3-(5-Bromothiophen-2-yl)-3-methylbutanoic acid (CAS 1225883-41-9), a certified reference material (molecular formula C9H11BrO2S, MW 263.15 g/mol) for analytical method development and quality control.
3-(5-Bromothiophen-2-yl)-3-methylbutanoic acid (C9H11BrO2S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system. 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.
