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)33-, 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]
ATMP has good antiscale performance. [3] [4] It is related structurally to nitrilotriacetic acid. [5]
