ATMP or aminotris(methylenephosphonic acid) is a phosphonic acid with chemical formula N(CH₂PO₃H₂)₃. It is a colorless solid. Its conjugate bases, such as [N(CH₂PO₃H)₃]^3-, have chelating properties.

ATMP can be synthesized from the Mannich-type reaction of ammonia, formaldehyde, and phosphorous acid, in a manner similar to the Kabachnik–Fields reaction.^[1]^[2]

Properties

ATMP has good antiscale performance.^[3]^[4] It is related structurally to nitrilotriacetic acid.^[5]
