Ethyl Tert-Butyl Ether (ETBE)
ETBE is an acyclic ether of monohydric ethanol and tert-butanol, used as a high-octane biofuel oxygenate. Classified at HTS 2909.19.18.00 as 'other' acyclic ethers, this chemically defined compound complies with Chapter 29 exclusion criteria and numerical order rules. It serves similar function to MTBE but with ethanol base.
