Copper Disodium EDTA (also known as Disodium Copper EDTA or CuNa₂EDTA) is a chelated complex formed between copper ions (Cu²⁺) and the disodium salt of ethylenediaminetetraacetic acid (EDTA). It is a stable, water-soluble coordination compound widely used in chemical, agricultural, and industrial applications.

Chemical Overview:

Formula: C₁₀H₁₂CuN₂Na₂O₈

Appearance: Typically a blue-green crystalline powder or granules

Solubility: Highly soluble in water

Function: Serves as a bioavailable source of copper while preventing copper precipitation or reactivity through chelation.

Key Uses in Chemical & Industrial Applications:

Agriculture & Fertilizers

Used in micronutrient fertilizers to correct copper deficiency in soils and crops. The EDTA ligand keeps copper soluble and plant-available across a range of pH levels.

Animal Feed Additive

Provides essential copper in a stable, non-toxic form for livestock nutrition.

Water Treatment

Controls trace metal activity; though less common than other EDTA salts, it can be used to manage copper levels in industrial water systems.

Cosmetics & Personal Care

Occasionally used as a color stabilizer or trace mineral source, though more common EDTA forms (e.g., disodium or tetrasodium EDTA) are preferred for sequestration.

Analytical & Laboratory Chemistry

Employed as a standard in calibration or as a controlled copper source in enzymatic studies.

Fungicide/Bacteriostatic Agent

In some formulations, it leverages copper’s biocidal properties in a stabilized form for antimicrobial action.

Unlike free copper salts (e.g., copper sulfate), Copper Disodium EDTA resists binding to soil particles or forming insoluble hydroxides, ensuring better bioavailability and consistent performance. However, environmental concerns about EDTA persistence have led to regulated use in some regions.

In summary, Copper Disodium EDTA is primarily valued as a stable, bioavailable copper delivery agent in agriculture, feed, and specialty chemical formulations.
