Product Application of 2,4-di-tert-butylphenol CAS#96-76-4
This substance works as a synthetic precursor for antioxidant products, stabilizer agents and UV absorbing additives. It delivers antioxidant and ultraviolet shielding performance, and acts as a vital starting material to prepare different light stabilizers and antioxidant varieties. Typical downstream outputs cover Antioxidant 168, Antioxidant P-EPQ, Light Stabilizer 120, UV-327 and UV-320 absorbers, alongside activators for recycled rubber. It may also be applied to develop intermediate compounds and plasticizers, and ranks as a primary feedstock when producing phosphite-type antioxidants.
