Used as a catalyst in organic synthesis, particularly in carbon-carbon bond formation reactions. Employed in the preparation of radiopaque materials for medical imaging due to its high density and iodine content. Applied in the formulation of disinfectants and antiseptics because of its antimicrobial properties. Utilized in electroplating processes to deposit zinc coatings on metals for corrosion protection. Also found in some types of dyes and as a reagent in analytical chemistry for detecting the presence of certain compounds.
