Cyanuric acid is widely used as a stabilizing agent in swimming pools and spas to maintain chlorine levels by protecting it from degradation caused by ultraviolet light. It helps to reduce the frequency of chlorine addition, making pool maintenance more efficient. In the plastics industry, it serves as a precursor in the production of melamine and other resins, which are essential for manufacturing laminates, adhesives, and coatings. Additionally, it is utilized in the synthesis of herbicides and disinfectants, contributing to agricultural and sanitation applications. Its ability to form stable complexes with certain metals also makes it useful in water treatment processes to control scale and corrosion.
