Chlorine Stabilizer (Cyanuric Acid)
CAS Number: 108-80-5
Cyanuric acid is a chlorine stabilizer used in outdoor swimming pools, water parks, and recreational water systems to protect free chlorine from rapid photodegradation by UV sunlight. It forms a reversible complex with free chlorine (hypochlorous acid), slowing UV-induced chlorine loss without significantly reducing its disinfection efficacy. Proper use of cyanuric acid can reduce chlorine consumption by up to 80% in outdoor pools.
