Chemical Structure
Description
3-Aminoisothiazole (C3H4N2S) contains a nitrile group, sulfur-containing functionality. Its physicochemical properties are representative of its class; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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).
CATO supplies 3-Aminoisothiazole (CAS 4592-62-5), a certified reference material (molecular formula C3H4N2S, MW 100.14 g/mol) for analytical method development and quality control.
