Diethylenetriaminepenta(methylene-phosphonic acid) (Cat No.:M085988) is a phosphonic acid-based chelating agent widely used in industrial water treatment, detergents, and oilfield applications. With multiple phosphonate groups and nitrogen atoms, DTPMP exhibits strong chelation toward metal ions like calcium, magnesium, and iron, effectively preventing scale formation and corrosion. It also demonstrates excellent thermal and hydrolytic stability, making it ideal for high-temperature environments such as boilers and cooling systems. DTPMP is commonly supplied as an aqueous solution and is environmentally persistent, requiring controlled use in compliance with regulatory standards for water treatment additives.
