Zinc bromide dihydrate is widely used in various industrial and chemical applications. It serves as a key component in the preparation of clear brine fluids for oil and gas well drilling, where it helps stabilize the wellbore and control formation pressures. In the field of organic chemistry, it acts as a Lewis acid catalyst, facilitating reactions such as alkylation and polymerization. Additionally, it is utilized in the production of photographic emulsions and as a corrosion inhibitor in cooling systems. Its hygroscopic nature makes it suitable for use in humidity control applications. In the energy sector, it is explored as an electrolyte in zinc-bromine batteries, offering potential for energy storage solutions.
