Product Description:

Trans-1,2-Cyclohexanediaminetetraacetic acid (CDTA) is a hexadentate chelating agent and a structural analog of ethylenediaminetetraacetic acid (EDTA). It is characterized by its cyclohexane backbone, which imparts greater rigidity and selectivity compared to EDTA. CDTA is typically available as a white crystalline powder and is known for its high stability constants with various metal ions, particularly transition metals and lanthanides. The primary application of CDTA is as a powerful chelating agent in analytical chemistry and materials science. It is extensively used to complex and remove interfering metal ions in analytical procedures, such as in titrations and spectrophotometric analyses. In materials chemistry, it serves as a functional component in the synthesis of adsorbents and separation materials, where its strong and selective metal-binding properties are leveraged for the purification of solutions, recovery of valuable metals, or the preparation of functionalized surfaces. Its ability to form stable complexes also makes it useful in buffer solutions for controlling metal ion activity. Due to its robust chelating ability, CDTA finds use in industrial processes, including water treatment and textile processing, to sequester metal ions that can cause undesired precipitation or catalysis. It is also employed in biochemical research to inhibit metalloenzymes. As a reagent, it is handled as a standard laboratory chemical with typical precautions for fine powders and acids.
