Description

1,6-Diaminohexane-N,N,N',N'-Tetraacetic Acid is a high-purity chelating agent and a derivative of ethylenediaminetetraacetic acid (EDTA). This compound is valued for its strong and selective metal ion sequestration capabilities, particularly for transition and heavy metals. It is essential for researchers and manufacturers in industries requiring precise metal control, such as pharmaceuticals, analytical chemistry, and specialty chemical synthesis.

Application

• Pharmaceutical Intermediates: Used in the synthesis of active pharmaceutical ingredients (APIs) and contrast agents where metal chelation is a critical step.
• Analytical Chemistry Reagent: Serves as a complexometric titrant and a masking agent in titrations and spectroscopic analyses to eliminate interference from metal ions.
• Biochemical Research: Employed in buffer systems and molecular biology applications to maintain metal-free conditions for enzyme studies and protein purification.
• Specialty Chemical Synthesis: Acts as a key ligand or building block in the production of advanced materials, catalysts, and metal-organic frameworks (MOFs).
• Water Treatment & Detergent Formulations: Functions as a sequestrant to control water hardness ions in industrial cleaning processes and specialty detergent formulas.
