Mono-Ammonium Phosphate (MAP)
Mono-Ammonium Phosphate (MAP)
Mono-Ammonium Phosphate (MAP) is a widely used chemical compound in industrial applications, including fertiliser production, water treatment, and flame retardants. Its high phosphorus content makes it an essential component in agricultural and industrial processes. It is typically produced by reacting ammonia with phosphoric acid, resulting in a stable, water-soluble product.
