2-(Benzo[d]isothiazol-3-yl)acetic acid CAS 29266-68-0

Description

Based on its molecular formula C9H7NO2S, 2-(Benzo[d]isothiazol-3-yl)acetic acid contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 193.22 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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).
