CAS 139-13-9: Nitrilotriacetic acid

Description: Nitrilotriacetic acid (NTA) is a chelating agent with the chemical formula C6H9N3O6. It is characterized by its ability to form stable complexes with metal ions, which makes it useful in various applications, including water treatment, agriculture, and as a component in detergents. NTA is a colorless, crystalline solid that is soluble in water, and it exhibits a pH-dependent behavior, with its chelating ability being most effective in alkaline conditions. The presence of three carboxylic acid groups allows it to effectively bind to divalent and trivalent metal ions, such as calcium, magnesium, and iron. NTA is often considered a more environmentally friendly alternative to other chelating agents like EDTA, as it is biodegradable under certain conditions. However, its use has raised environmental concerns due to its potential to mobilize heavy metals in soil and water systems. Overall, NTA is a versatile compound with significant industrial and environmental relevance.
