General Description

Tri-o-tolyl phosphite, also known as TTOP, is a chemical compound used primarily as a stabilizer in the production of polymers and plastics. It is a colorless to pale yellow liquid with a slight aromatic odor, and its molecular formula is C21H21O3P. TTOP is highly effective as an antioxidant and thermal stabilizer, helping to prevent degradation and discoloration of polymers during processing and use. It is also used in the production of synthetic resins, elastomers, and adhesives. Furthermore, it has applications in the production of rubber and in the pharmaceutical industry as a reagent for the synthesis of organic compounds. Despite its numerous industrial applications, TTOP should be handled and stored with caution due to its potential for skin and eye irritation, as well as its flammability.
