1-Butene oxide (CAS 106-88-7)

1-Butene oxide, also known as butylene oxide or 1,2-epoxybutane, is a four-carbon epoxide with the molecular formula C4H8O. This organic compound features an ethylene oxide-like ring, specifically an oxygen atom bridging two adjacent carbon atoms, creating a three-membered ring structure that imparts significant strain and reactivity to the molecule. In chemical research, 1-butene oxide is primarily studied for its role as a reactive intermediate in the synthesis of a wide range of chemical products, including pharmaceuticals, polymers, and fine chemicals. The strained epoxide ring in 1-butene oxide is highly reactive and can undergo ring-opening reactions, which are facilitated either by acid or base catalysis, leading to the formation of diols, alcohols, and other oxygen-containing functional groups. This reactivity makes it valuable for creating complex molecular architectures through straightforward synthetic routes. Additionally, researchers utilize 1-butene oxide in the study of polymer chemistry, particularly in the production of polyethers and other epoxy-derived materials that require controlled ring-opening polymerization techniques to achieve desired properties like flexibility, resistance, and durability. The compound′s volatility and reactivity also make it a subject of safety and environmental impact studies, particularly regarding its behavior and effects when released into the atmosphere.
