Potassium Permanganate, free-flowing and 97% pure, is a versatile, high-grade oxidizing agent with numerous applications. This dark purple crystalline compound, also known as KMnO4, easily dissolves in water to create a from a light pink to a vibrant purple solution. Commonly used for water purification and treatment, it effectively removes iron, manganese, and other impurities by converting them to insoluble oxides that are easily filtered. Additionally, potassium permanganate supports aquaculture and fish tank maintenance, helping to maintain clean and safe water for aquatic environments. Ideal for use in a range of technical applications, it can also assist in green sand filter regeneration. This free-flow formulation ensures easy measurement and handling. Made in the USA, it meets high standards for quality and performance. Important Information: Potassium permanganate is a strong oxidizer and must be used with care. CAS # [7722-64-7].
