Used primarily as a chemical intermediate in organic synthesis, 2,3-epoxybutane serves in the production of specialty polymers and fine chemicals. Its strained epoxide ring allows ring-opening reactions, making it valuable in creating chiral building blocks for pharmaceuticals and agrochemicals. It is also employed in the synthesis of surfactants and modifiers for resins and coatings. Due to its reactivity, it enables the introduction of functional groups in complex molecule construction, particularly in asymmetric synthesis where stereochemistry plays a critical role.
