4-tert-Butylcatechol application
Polymerization Inhibitor
4-tert-Butylcatechol is an inhibitor for the polymerization of monomers such as styrene and other reactive monomers. It helps to prevent the unintended polymerization of these monomers during storage and transportation, thereby extending their shelf life.
Stabilizer
It is a stabilizer in the production of certain polymers and resins, particularly those vulnerable to autoxidation, such as polyvinyl chloride (PVC) and other polymers containing unsaturated bonds. TBC helps in preventing degradation and prolonging the service life of these polymers.
Antioxidant
4-tert-Butylcatechol acts as an antioxidant in the rubber industry. It helps to prevent the degradation of rubber products due to oxidation, thereby extending their durability and lifespan.
Chemical Intermediate
TBC is also an intermediate in the synthesis of various organic compounds. It serves as a building block in the production of certain pharmaceuticals, agrochemicals, and other specialty chemicals.
