Lithium sulfate

Lithium sulfate (CAS 10377-48-7), also marketed as lithium sulphate, is an inorganic lithium salt used across pharmaceutical, biotechnological, and industrial water treatment applications. It functions primarily as a source of lithium ions in controlled chemical environments and as a selective biocidal and catalytic agent in various manufacturing processes.

In pharmaceutical manufacturing, it serves as a reagent and process chemical in the production of lithium-based active ingredients, particularly for psychiatric and neurological drug formulations. Biotechnology and life sciences applications include its use as a protein crystallization agent, where controlled ionic conditions are critical for structural analysis and drug discovery workflows.

Water treatment operations employ it as a biocidal additive to inhibit microbial growth in industrial cooling systems and process water circuits throughout the facility. It also functions as a catalyst precursor in select inorganic synthesis processes, where lithium ion activity influences reaction selectivity and yield during the production cycle.

The product is available as a white crystalline powder in both anhydrous and monohydrate forms. Standard supply grades include technical grade for industrial applications and high-purity grades. These high-purity options meet pharmaceutical and reagent specifications. Packaging typically ranges from laboratory-scale quantities to bulk industrial supply depending on requirements.
