Description

trans-1,2-Diaminocyclohexane-N,N,N',N'-Tetraacetic Acid Monohydrate is a high-purity chelating agent and a derivative of ethylenediaminetetraacetic acid (EDTA), where the ethylene bridge is replaced by a rigid 1,2-diaminocyclohexane group. This structural modification enhances its metal ion selectivity and binding affinity, particularly for transition and lanthanide metals, making it a critical component in advanced chemical and biochemical processes. It is essential for researchers and manufacturers in pharmaceuticals, analytical chemistry, and industrial catalysis who require precise metal ion control and complexation.

Application

• Pharmaceutical Intermediate: Used in the synthesis of contrast agents for magnetic resonance imaging (MRI) and in the development of novel metal-based therapeutics.
• Analytical Chemistry Reagent: Serves as a highly selective masking agent and complexometric titrant in the analysis of metal ions via titration, spectroscopy, or chromatography.
• Catalyst Ligand: Acts as a chiral ligand in asymmetric synthesis and homogeneous catalysis for the production of fine chemicals and active pharmaceutical ingredients (APIs).
• Biochemical Research: Employed in buffer systems to maintain metal-free conditions in enzymatic studies and protein purification.
• Industrial Water Treatment: Functions as a scale inhibitor and sequestrant in high-temperature or specialty boiler water systems where conventional chelants are ineffective.
• Polymer Stabilization: Used as a metal deactivator to prevent catalytic degradation in plastics and synthetic fibers during processing.
