Usage

General Description

4,4-Bis(diethylphosphonomethyl)biphenyl, also known as Bisphosphonate, is a phosphonate compound commonly used as a flame retardant and a chelating agent. It is a colorless to pale yellow liquid with a high boiling point, making it suitable for various industrial applications. The chemical is highly stable and has a low water solubility, making it a durable and effective flame retardant for plastics, textiles, and other materials. Additionally, it can be used as a chelating agent to bind and remove metal ions in industrial processes and water treatment. However, due to its potential toxicity and environmental concerns, its use and disposal must be carefully managed to ensure safety and minimize negative impacts.
