For professionals in chemistry and related industries, a deep understanding of key chemical compounds is essential for successful research, development, and manufacturing. CDTA, or Cyclohexanediaminetetraacetic Acid (CAS 482-54-2), is a significant chelating agent with a range of valuable applications. This guide provides an overview of its properties, common uses, and strategic approaches for sourcing this chemical from reputable manufacturers.

Key Properties of CDTA

CDTA is an organooxygen compound belonging to the family of aminocarboxylic acids. Its molecular structure features a cyclohexane ring with two amine groups, each substituted with two carboxymethyl groups. This arrangement grants CDTA its potent chelating capabilities, allowing it to form highly stable complexes with various divalent and trivalent metal ions. Typically appearing as a white solid, its properties include:

  • Molecular Formula: C14H22N2O8
  • Molecular Weight: Approximately 346.33 g/mol
  • Melting Point: Around 215 °C
  • Purity: Commonly available at 95% or higher.
  • Acidity Factor (pKa): Predicted values around 1.78±0.10.

These properties make CDTA a robust and reliable choice for many chemical processes.

Applications Driven by Chelation

The primary function of CDTA is its ability to effectively chelate metal ions. This characteristic underpins its use in several critical areas:

  • Phytoextraction: As previously discussed, CDTA is instrumental in environmental science for extracting heavy metals from contaminated soils, making them more accessible for plant uptake.
  • Analytical Chemistry: It serves as a highly accurate titrant for determining the concentration of metal ions in solution, crucial for quality control and research laboratories.
  • Industrial Processes: CDTA can be used in specialized water treatment applications or as a stabilizing agent in formulations where metal ion activity needs to be controlled.

When considering to purchase CDTA, understanding the specific requirements of your application will guide your choice of purity and grade.
