Used as a reactive intermediate in organic synthesis, particularly in the production of specialty polymers and resins. It serves as a building block for synthesizing polyether glycols and crosslinking agents in coatings and adhesives. Due to its strained epoxide ring, it readily undergoes ring-opening reactions with nucleophiles, making it valuable in pharmaceutical synthesis and fine chemical manufacturing. Also employed in the preparation of electrolytes for lithium-ion batteries and as a modifier in epoxy resin systems to improve flexibility and adhesion.
