Basic lead phosphite
# Basic lead phosphite

Basic lead phosphite is an inorganic compound with the proposed composition $Pb_3O(OH)_2(HPO_3).$ The compound contains the phosphite anion, which provides the reducing properties associated with the application of this material.

It is widely used as a stabilizer for chlorine-containing polymers, especially polyvinylchloride. Other lead phosphites are known, including normal lead phosphite, $PbHPO_3,$ although the basic salt is especially effective.
