Butylene Oxide (1,2-Epoxybutane) from Germany
Butylene oxide is a simple aliphatic epoxide with a three-membered ring, employed as a monomer in polyether production and as a sterilizing agent. It qualifies for HTS 2910.90.91.00 as an 'other' epoxide, explicitly covered despite chapter note exclusions for certain cyclic forms. The compound's volatility requires stabilized packaging for safe transport.
