Pentetic acid or diethylenetriaminepentaacetic acid (DTPA) is a pentacarboxylic acid, being a conjugate acid of a pentetate(1-). More specifically, it is an aminopolycarboxylic acid with a backbone of diethylenetriamine and five groups of carboxymethyl. It exists as a solid compound that is white in color and dissolves partially in water.
