Product Description
Azulene (CAS No. 275-51-4) is a bicyclic non-benzenoid aromatic hydrocarbon with the molecular formula C₁₀H₈ and a molecular weight of 128.17 g/mol. It is structurally characterized by a fused five-membered and seven-membered carbon ring system. Unlike many common aromatic hydrocarbons, azulene exhibits a distinctive deep-blue color due to its electronic structure.
Azulene is an important compound in organic chemistry research because of its unusual aromaticity, electronic properties, and optical characteristics. It is used in studies involving organic synthesis, functional materials, molecular electronics, and photophysical chemistry. Its derivatives are also investigated for potential applications in advanced materials and specialty chemical development.
