Species-linked diamine triacetic acids and their chelates
First Claim
1. A reagent for use in the fluorometric quantification of a biologically active organic species comprising a diamine triacetic acid having the structural formula:
- ##STR11## wherein R is a two to eight atom covalent bridge selected from carbon-oxygen ether bridges, carbon-nitrogen secondary and tertiary amide bridges and carbon-carbon alkylene, cycloalkylene and arylene bridges, T is the biologically active organic species to be fluorometrically quantified, T being other than an aliphatic mono- or polyamine, or aliphatic mono- or polyol, but comprising at least one originally present or added primary amine, secondary amine, thiol or hydroxyl functional group, and L is said at least one functional group in deprotonated form covalently bonding T to the indicated carbonyl carbon of the diamine triacetic acid.

Abstract
Species-linked diamine triacetic acids of the formula ##STR1## wherein T is an organic species containing at least one amine, hydroxyl, or thiol functional group, L is the residue of at least one of those functional groups and R is a two or more atom long covalent bridge, are disclosed. Methods for their preparation, for the preparation of metal chelates from them and for the use of the chelates are also disclosed. In a preferred embodiment, the metal ions employed in the formation of the chelates are rare earth metal ions capable of forming fluorescent chelates which can in turn be employed in fluoroassay techniques.
