General Description

Triheptyl phosphate is an organic compound with the chemical formula C21H46O4P, consisting of a phosphate group attached to a chain of seven carbon atoms. It is commonly used as a plasticizer in various applications, particularly in the production of vinyl and other plastics. Triheptyl phosphate helps improve the flexibility, durability, and fire resistance of plastic materials by reducing their brittleness and increasing their resistance to burning. However, it may pose health risks when inhaled or ingested, as it can irritate the respiratory system and cause nausea, vomiting, and other adverse effects. Therefore, it is important to handle and store triheptyl phosphate with caution and adhere to proper safety procedures when working with this chemical.
