Azulene is a blue crystalline compound with the chemical formula C10H8 and a melting point of 99°C. It contains afive-membered ring fused to a seven-membered ring and has aromatic properties. When heated it is converted into naphthalene.
Uses
Azulene is used as an additive in ointments. It is an active ingredient in cosmetics, shaving creams and other topicals. It is used as antioxidant and in anti-inflammatory activities. It is involved in the colorimetric determination of furfural. It acts as ligand for low valent metals and forms pi complexes with both cyclopentadienyl and cylcloheptatrienyl ligands in organometallic chemistry. It is also used as precursor for the preparation of (azulene)Mo2 (CO)6 and (azulene)Fe2 (CO)5.
Uses
azulene is renowned as an anti-inflammatory, calming, and soothing agent. excellent for sensitive skin, azulene is a german chamomile derivative with a characteristic deep blue color. Careful, it stains!
