Used as a flux in soldering and galvanizing processes to remove oxides from metal surfaces, ensuring strong and clean joins. Acts as a catalyst in organic synthesis, particularly in the Fischer indole synthesis and other condensation reactions. Employed in the production of wood preservatives due to its ability to inhibit fungal and insect damage. Utilized in aqueous solutions as a disinfectant and in laboratories for the preservation of tissues. Found in some types of deodorants and antiseptics due to its antimicrobial properties. Also serves as an electrolyte in dry-cell batteries and other electrochemical applications.
