Chemical Structure
Description
Owing to a nitrile group, sulfur-containing functionality, chlorine/iodine substitution, 6-Chloro-5-iodo-2-(methylthio)pyrimidin-4-amine is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 301.54 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).
