[1-({6-[(6-Aminohexyl)amino]hexyl}amino)-1,5-pentanediyl]bis(phosphonic acid)(CAS: 35657-77-3)

The compound is a white crystalline solid with a molecular weight of approximately 452.46 g/mol. It has a low solubility in water but can dissolve in organic solvents. The compound is known for its reactivity, particularly in forming stable complexes with metal ions and its use in chelating agents. It exhibits poor thermal stability and may decompose at higher temperatures.

The compound is synthesized through multi-step chemical reactions, starting from hexanediamine and 6-amino-hexanoic acid. The synthesis involves condensation reactions, amination, and amidation steps, with careful control of pH and temperature to achieve yield and selectivity. Commonly, the use of catalytic amounts of acid or base is necessary to ensure the reaction progresses to completion.

This compound is used in various industries, including pharmaceuticals for drug delivery systems and metal chelation therapy, polymers for stabilizing properties, sensors for detecting metal ions, and semiconductors for etching solutions. It is also utilized in water treatment for its ability to form stable complexes with metal ions, reducing corrosion and scaling.

Proper personal protective equipment (PPE) should be worn, including gloves, goggles, and a lab coat. Work should be conducted in a well-ventilated area or a fume hood to minimize inhalation exposure. Spills should be managed carefully using absorbent materials, and the area should be thoroughly cleaned with water. Safety data sheets (SDS) should be consulted for detailed handling instructions and emergency response procedures.
