Thallium(I) sulfate is  used as  very effective rodenticide against mice and rats. Since very dangerous, thallium(I) sulfate is forbidden in many european countries; however thallous sulfate is still in extensive use in South America and Asia, and also to some degree in the Souther regions of the United States.

Thallous sulfate is used in several industries as manufacturing of imitation jewelry pigments; of special alloy anode plates; of fireworks. Thallous sulfate is also used in semiconductors, scintillation counters, optical lenses, low-temperature thermometers etc.
