ATMP or aminotris is a phosphonic acid with chemical formula N₃. It is a colorless solid. Its conjugate bases, such as ^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.
