Lithium hypochlorite

Lithium hypochlorite: LiClO, is a colorless crystalline solid. It is used as a disinfectant for pools and a reagent for some chemical reactions.

Safety
Doses of 500 mg/kg cause clinical signs and significant mortality in rats. The use of chlorine-based disinfectants in domestic water, although widespread, has led to some controversy due to the formation of small quantities of harmful byproducts such as chloroform. Studies showed no uptake of lithium if pools with lithium hypochlorite have been used.
