ABSTRACT:
Chelating agents having in addition to their metal sequestering groups a functional group capable of reacting with bio-organic molecules are disclosed, in particular, substituted ethylenedinitrilotetraacetic acids such as 1-p-nitrophenylethylenedinitrilotetraacetic acid, 1-p-aminophenylethylenedinitrilotetraacetic acid and their derivatives are disclosed. These compounds are effective chelating agents and in addition are useful in the perturbed angular correlation method of studying molecular behavior.
