Description

Compared with other compounds in its class, the molecular weight of 263.15 g/mol gives 4-(3-Bromo-5-methylthiophen-2-yl)butanoic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

4-(3-Bromo-5-methylthiophen-2-yl)butanoic acid (CAS 1496290-57-3) is a high-purity analytical reference standard with the molecular formula C9H11BrO2S and a molecular weight of 263.15 g/mol.

The molecular framework of 4-(3-Bromo-5-methylthiophen-2-yl)butanoic acid (C9H11BrO2S) is characterized by a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
