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.

The aim of this study was to assess interactions of EDTA and citric acid (CA) with sodium hypochlorite (NaOCl), the indispensable endodontic irrigant. Other chelators were simultaneously evaluated as possible alternatives: sodium triphosphate (STP), amino tris methylenephosphonic acid (ATMA), and
