Lithium benzoate, the lithium salt of benzoic acid, is a specialty chemical primarily used as a corrosion inhibitor in industrial applications such as coolants, antifreeze, and metalworking fluids, where it helps prevent rust and degradation. In the pharmaceutical sector, it serves as an alternative source of lithium for mood stabilization in treating bipolar disorder and other psychiatric conditions, though lithium carbonate is more commonly prescribed. It is also utilized in the formulation of lubricants and greases to enhance thermal stability and performance. Additionally, lithium benzoate acts as an intermediate or reagent in organic synthesis for producing pharmaceuticals, agrochemicals, and other fine chemicals.
