(1-Hydroxy-1,1-ethanediyl)bis(phosphonic acid)(CAS: 2809-21-4)

(1-Hydroxy-1,1-ethanediyl)bis(phosphonic acid), also known as ethane-1,1-diyldiphosphonic acid (CAS: 2809-21-4), is a diphosphonic acid with the chemical formula C2H11O11P2. It is a white, crystalline solid that is highly soluble in water and exhibits strong chelating properties. The compound is characterized by its two phosphonic acid groups connected via an ethane bridge with a hydroxyl group, making it effective in binding metal ions and stabilizing chemical structures.

(1-Hydroxy-1,1-ethanediyl)bis(phosphonic acid) (CAS: 2809-21-4) is widely used in pharmaceuticals as a bone resorption inhibitor, in industrial settings as a corrosion inhibitor and scale control agent, and in research for its chelating properties. It also serves as a precursor in the synthesis of other phosphonic acid derivatives and is employed in water treatment processes to remove heavy metals and prevent fouling in pipelines.

Safety of (1-Hydroxy-1,1-ethanediyl)bis(phosphonic acid) (CAS: 2809-21-4) requires caution. It is toxic if ingested or inhaled and can cause skin and eye irritation. Handling should involve protective equipment such as gloves, goggles, and lab coats. Safety standards emphasize proper ventilation and adherence to OSHA guidelines to minimize exposure. Always follow recommended safety protocols to ensure safe use in laboratories or industrial environments.

(1-Hydroxy-1,1-ethanediyl)bis(phosphonic acid) (CAS: 2809-21-4) should be stored in a cool, dry place (ideally below 25°C), away from moisture and direct light. Use airtight, corrosion-resistant containers to maintain stability. Ensure storage in a well-ventilated area and keep it inaccessible to children. Regularly check for signs of degradation to preserve its chemical integrity and effectiveness.
