What is Hydroxyphosphono-acetic Acid CAS 23783-26-8?
Hydroxyphosphono-acetic Acid (HPA) CAS 23783-26-8 is a high-performance organophosphorus scale and corrosion inhibitor widely used in industrial water treatment. It contains both phosphonic and carboxylic functional groups, giving it excellent chelating ability, thermal stability, and resistance to hydrolysis. HPA is highly effective in preventing calcium carbonate, calcium phosphate, and calcium sulfate scale, while also providing good corrosion inhibition.
