Lithium sulfate

Lithium sulfate (Li2SO4, CAS 10377-48-7) is an inorganic lithium salt available under trade names including Lithiophor. It carries no E-code designation and is classified under HS code 28332990. The anhydrous form and monohydrate are both commercially available.

In pharmaceutical and biotechnology applications, lithium sulfate acts as a crystallization agent for proteins, promoting ordered crystal formation by stabilizing hydrophobic interactions in solution. In water treatment, it functions as an antimicrobial additive, where the lithium ion interferes with microbial metabolic pathways to suppress biological growth.

Lithium sulfate is supplied as a white crystalline powder in pharmaceutical-grade and technical-grade specifications, with compliance available against Ph.Eur. monographs and REACH registration requirements. Standard packaging includes multi-layer bags and fiber drums sized for industrial procurement volumes. Buyers should confirm grade suitability against their specific regulatory framework prior to ordering.
