2-Tert-butyl-4-hydroxyanisole

2-tert-Butyl-4-hydroxyanisole, commonly abbreviated as 2-BHA or TBMP, is a synthetic phenolic antioxidant with the molecular formula C11H16O2. It is the minor isomer component of the commercial BHA mixture (CAS 25013-16-5) and is often referenced alongside its 3-BHA counterpart in food-grade and industrial antioxidant specifications.

In food and nutrition applications, 2-BHA inhibits lipid oxidation by donating hydrogen atoms to free radicals, interrupting chain reactions that cause rancidity in fats and oils. In polymer and lubricant formulations, it functions as a process stabilizer, protecting base materials from oxidative degradation during high-temperature processing or extended storage.

This material is supplied to meet relevant food additive and industrial purity standards, including FCC and REACH compliance requirements. It is available in solid form for bulk industrial procurement. Buyers should confirm isomer ratio specifications when sourcing for regulated food or cosmetic applications. HS code 2909500000 applies for EU import classification.
