1.2 Cyclohexylenedinitrilo Tetraacetic Acid
Description
This 1.2 Cyclohexylenedinitrilo Tetraacetic Acid chelating agent is supplied for laboratory analysis industrial cleaning and metal ion control applications.
1,2-Cyclohexylenedinitrilotetraacetic acid (CDTA or DCTA) is a white, solid chelating agent (C14H22N2O8cap C sub 14 cap H sub 22 cap N sub 2 cap O sub 8
𝐶14𝐻22𝑁2𝑂8
) with a high purity (typically 98-99.5%) and melting point of 213–216 °C. It acts as a powerful multidentate ligand for metal ions, notably for complexometry, analytical chemistry (like TITRIPLEX IV), water softening, and to treat manganese toxicity in laboratories.
Key Characteristics and Applications
- Chelating Agent: Similar to EDTA but with stronger, more selective binding for alkaline earth metals and lanthanides.
- Analytical Use: Used in Total Ionic Strength Adjustment Buffer (TISAB) solutions for ISE measurements and in capillary electrophoresis.
- Properties: Partially soluble in water; soluble in 1N Sodium Hydroxide and alkali solutions.
- Safety: Causes skin and serious eye irritation.
