Chemical Structure
Description
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, chlorine substitution, 2-Chloro-6-(p-tolylthio)-1H-purine is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 276.74 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).
