CAS 275-51-4: Azulene

Azulene (Bicyclo[5.3.0]Decapentaene) is a natural product.

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. This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio.

Azulene

Cyclopentacycloheptene is a model system that has been used to study the transport properties of azulene. It has also been used to measure the detection sensitivity of fluorescence probes and as a fluorescent label for esters. Cyclopentacycloheptene can be synthesized by reacting trifluoroacetic acid with azulene, or it can be extracted from plants in the genus Acacia. This compound is an inorganic acid and may cause allergic symptoms such as skin rash or itching when it is touched. Cyclopentacycloheptene is soluble in acetone but insoluble in water, which makes it useful for extracting compounds from plants with high concentrations of acetate extract.
