DTPA-tetra (t-Bu ester) (Cat No.: M134107) is a protected derivative of diethylenetriaminepentaacetic acid (DTPA), where four carboxyl groups are esterified with tert-butyl groups. This esterified form enhances solubility in organic solvents and improves stability, making it useful in chelation chemistry and metal complexation studies. It serves as an intermediate in the synthesis of metal chelators for medical imaging, radiopharmaceuticals, and contrast agents. Upon hydrolysis, it regenerates the free DTPA ligand, which has applications in metal ion sequestration and detoxification therapies.
