FAQ

What is Triisobutyl phosphate (CAS: 126-71-6)?

Triisobutyl phosphate (CAS: 126-71-6) is an organic phosphorus compound with the chemical formula C15H31O4P. It is a colorless, viscous liquid with low volatility and is commonly used as a plasticizer and stabilizer. Its structure consists of a central phosphate group attached to three isobutyl groups, making it suitable for various industrial applications.

What are the main uses of Triisobutyl phosphate (CAS: 126-71-6)?

Triisobutyl phosphate (CAS: 126-71-6) is primarily used as a plasticizer in polyvinyl chloride (PVC) products, enhancing flexibility and durability. It also serves as a flame retardant additive, a stabilizer in organic compounds, and a component in pharmaceutical formulations. Additionally, it finds application in research and industrial processes involving phosphorus-based chemistry.

Is Triisobutyl phosphate (CAS: 126-71-6) safe?

Triisobutyl phosphate (CAS: 126-71-6) is generally considered safe when handled properly, but it should be treated with caution. It has low toxicity but may cause skin or eye irritation. Safety standards recommend using appropriate protective equipment, such as gloves and goggles, and ensuring proper ventilation during handling. Always follow established safety guidelines for chemical exposure.

How should Triisobutyl phosphate (CAS: 126-71-6) be stored?

Triisobutyl phosphate (CAS: 126-71-6) should be stored in a cool, dry, and well-ventilated area, away from direct sunlight. It is stable under normal storage conditions but should be kept in a sealed container to prevent moisture absorption. Maintain storage temperature below 25°C and ensure humidity levels are controlled to preserve its chemical integrity.
