Application
Nitrilotri(methylphosphonic acid) is a common chelating agent used in synthetic chemistry. Some of the other applications include:
- Preparation of hexagonal porous three-dimensional structures encapsulating a template, layered structures with intercalated templates or linear polymers.
- Synthesis of metal-organic frameworks in combination with uranyl nitrate.
- Preparation of ingredient of anticorrosive protective coatings on the steel surface.
- ATMP can also be employed as a scale inhibitor during squeeze treatments in oilfield operations.
