Nitrilotriacetic Acid(NTA ACID)139-13-9

Nitrilotriacetic acid (NTA ACID) is the aminopolycarboxylic acid with the formula N(CH2CO2H)3. It is a colourless solid that is used as a chelating agent, which forms coordination compounds with metal ions (chelates) such as Ca2+, Cu2+, and Fe3+. NTA can sequester metal ions to form water-soluble complexes; it is an important chelating agent, with many industrial applications.
