Application

Lithium chloride (2.3% in Tetrahydrofuran, ca. 0.5mol/L) serves multiple essential purposes due to its unique chemical properties. This product's primary role is as a critical reagent in various chemical processes, notable for its high solubility in water and polar organic solvents. It is integral in producing lithium metal through electrolysis, where its use in a lithium chloride-potassium chloride eutectic allows low-temperature operations in brazing fluxes and baths. Furthermore, lithium chloride is vital in organic synthesis, particularly as an additive in the Stille reaction and for the selective precipitation of RNA from cellular extracts. Its deliquescent nature makes it an excellent desiccant for air streams in industrial drying and air conditioning systems, relying on its characteristic of forming concentrated solutions that correlate directly with atmospheric humidity, thus serving as a calibration standard for hygrometers. Moreover, it plays a role in the preparation of buffers for immunoprecipitation and radioimmunoprecipitation assays, demonstrating its versatility in biochemical applications, including assays studying cell fate and neurobiology. Additionally, its application extends to pyrotechnics, generating a vibrant red flame, and it acts as a flux in welding and brazing of aluminum, particularly relevant in the automotive industry.
