1,3-Diamino-2-hydroxypropane-N,N′,N′′,N′′′-tetraacetic acid

Description:
1,3-Diamino-2-hydroxypropane-N,N′,N′′,N′′′-tetraacetic acid, commonly known as DTPA (diethylenetriaminepentaacetic acid), is a chelating agent that forms stable complexes with metal ions. It features multiple amine and carboxylic acid functional groups, which enhance its ability to bind to various metal ions, making it useful in applications such as metal ion sequestration, radiopharmaceuticals, and as a contrast agent in medical imaging. The compound is typically a white crystalline solid that is soluble in water, reflecting its polar nature due to the presence of hydroxyl and carboxyl groups. DTPA is often utilized in analytical chemistry for the determination of metal concentrations and in environmental applications to remediate heavy metal contamination. Its ability to form stable complexes with metals like calcium, magnesium, and iron is significant in both biological systems and industrial processes. Safety considerations include handling it with care, as with many chelating agents, due to potential toxicity and environmental impact.
