Chemical Structure
Description
1,2-Epoxy-5-cyclooctene 1,5-Cyclooctadiene monoepoxide 5,6-Epoxy-1-cyclooctene 637-90-1 9-Oxabicyclo[6.1.0]non-4-ene NSC-61254 NSC61254 (C8H12O) contains a hydroxyl group, an ether linkage. Its physicochemical properties are representative of its class; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
