Applications

1. Chelating Agent

Commonly used to bind metal ions such as Fe³⁺, Cu²⁺, Zn²⁺, and Ni²⁺.

Forms part of chelating resins for water softening and metal ion removal in wastewater treatment.

2. Precursor for Chelating Resins

IDA is a core component in the production of IDA-functionalized resins, such as those used in immobilized metal affinity chromatography (IMAC) - critical in protein purification, especially for His-tagged proteins.

3. Pharmaceutical Intermediate

Used in the synthesis of radiopharmaceuticals for diagnostic imaging, including hepatobiliary imaging agents like IDA derivatives labeled with technetium-99m (99mTc).

4. Micronutrient Fertilizers

Serves as a chelating agent in agriculture to provide bioavailable forms of trace metals (e.g., Fe, Zn, Mn), especially in alkaline soils.

5. Industrial Cleaning Agents

Included in formulations for descaling, boiler cleaning, and detergents where metal ion removal is needed.

6. Electroplating and Metal Processing

Controls metal ion concentrations in plating baths, improving deposition quality and reducing metal waste.
