Used primarily as an intermediate in organic synthesis, especially in the production of antioxidants like butylated hydroxytoluene (BHT). It serves as a building block in alkylation reactions and is involved in the manufacture of flavors and fragrances due to its reactive double bond. Also utilized in research settings for studying reaction mechanisms involving alkenes, such as electrophilic addition and ozonolysis. Its volatility and reactivity make it suitable for use in certain polymerization processes and as a reagent in laboratory-scale syntheses.
