Used primarily as a fungicide and bactericide in various industrial, agricultural, and laboratory applications. It is effective in controlling microbial growth in paints, coatings, thinners, wood preservatives, and paper production processes. In laboratories, it serves as a reagent for biochemical research, particularly in studies involving enzyme inhibition and protein analysis. Additionally, it has been utilized in the preservation of biological specimens due to its antimicrobial properties. However, its use is limited and regulated due to toxicity concerns associated with mercury compounds, and it should be handled with caution to avoid adverse health and environmental impacts.
