Description
Tert-butyl acetate (CAS 540-88-5, EC 208-760-7), also known as TBAC and NSC 59719, is an ester solvent with the molecular formula C6H12O2. It carries no E-code designation and is classified under HS code 29153990.
In pharmaceutical manufacturing, tert-butyl acetate functions as a reaction solvent and carrier, facilitating active ingredient dissolution and controlled release in formulations. In personal care, it acts as a solvent carrier for fragrance compounds, improving dispersion and skin adhesion. It also serves as a catalyst medium in select esterification reactions within food-grade flavoring production.
Tert-butyl acetate is available in technical and high-purity grades, with compliance documentation available for REACH-registered supply chains. Procurement teams should confirm FCC or Ph.Eur. grade requirements prior to ordering, as specifications vary by application. Standard packaging includes drums and IBC containers for bulk industrial supply.
