Gasoline antiknock additive (traditional largest use): raises octane as a lead replacement; gradually displaced by ethanol gasoline and alkylate but still exported from some capacities 2. Chemical intermediate: high-temperature cracking to high-purity isobutene (butyl rubber / MMA feedstock); pharma and agrochemical intermediates 3. Industrial/lab extractant and reaction solvent: low-polarity extraction of oils, alkaloids and fragrances; low-boiling recoverable synthesis solvent; specialty paint/oil cleaners 4. Historical medical niche: former minimally invasive gallstone solvent — rarely used clinically now
