4-tert-Butylcatechol (TBC) is a chemical substance widely used in the industrial field, with its core applications concentrated in two major areas: polymerization inhibitors and antioxidants, and extending to other fine chemical industries. ‌
Polymerization inhibitors:
4-tert-Butylcatechol (TBC) is an efficient inhibitor for the distillation or storage of olefin monomers, especially in unsaturated monomers such as styrene, butadiene, and chloroprene. Its polymerization inhibition efficiency is 25 times higher than that of hydroquinone at 60 ℃, making it suitable for the production of vinyl monomers such as styrene, butadiene, vinyl chloride, as well as polymers such as polyurethane. ‌
Antioxidants:
4-tert-Butylcatechol (TBC) can be used as an antioxidant for polymers such as polyethylene, polypropylene, synthetic rubber, nylon, and can also be used as an antioxidant for compounds such as oils, ethyl cellulose, lubricants, and caprolactam. Its antioxidant properties can extend the service life of materials and improve stability. ‌
Other uses:
4-tert-Butylcatechol (TBC) is also used as a stabilizer for insecticides, a passivator for polyurethane catalysts, and a stabilizer for organic compounds. For example, chemical stability can be enhanced in insecticide formulations, and side reactions can be suppressed in catalyst systems. ‌

Store in a cool, dry, and ventilated warehouse, away from sources of fire and heat; Avoid mixing storage with oxidants, acids, etc.
