Hydroxyethylidene diphosphonic acid (HEDP) is a new type of chlorine-free electroplating complexing agent. It is used as the main agent for stable water quality in the circulating cooling water system, and plays the role of corrosion and scale inhibition. This product is one of the organic polyphosphonic acid-free water tablet conditioners. There are also some other varieties of such products produced in China, such as aminotrimethylenephosphonic acid (ATMP): [CH2PO(OH)2]3N and e-thyl acatate Diaminetetramethylenephosphoric acid (EDTMP) and so on. Organic polyphosphonic acid is a type of water treatment agent developed in the late 1960s and confirmed around the 1970s.

1-Hydroxyethylidenebis(phosphonic acid) acts as human protein tyrosine phosphatase inhibitor. It is also useful for photographic applications. It finds application to strengthen bone, osteoporosis treatment and to treat Paget's disease of bone. In addition, it is used in corrosion inhibition in circulating cool water systems, oil fields and low-pressure boilers with electric power, the chemical industry, metallurgy and fertilizers. It is also utilized for formulating reverse osmosis and thermal desalination anti-scaling agents. Furthermore, it is used in detergents, water treatment, cosmetics and pharmaceuticals.
