Azulene

Description:

Azulene is a bicyclic aromatic hydrocarbon characterized by its unique blue color, which distinguishes it from many other organic compounds. It has a molecular formula of C10H8 and features a non-alternant structure, consisting of a fused five-membered and seven-membered ring. This structure contributes to its distinct electronic properties, including a significant dipole moment and unusual reactivity compared to typical aromatic compounds. Azulene is known for its stability and is less prone to undergo electrophilic substitution reactions, which are common in other aromatic systems. It exhibits interesting photophysical properties, making it useful in various applications, including organic electronics and as a dye. Azulene is also found in some essential oils and has been studied for its potential biological activities. Its CAS number is 275-51-4, which is used for identification in chemical databases. Overall, azulene's unique structure and properties make it a subject of interest in both theoretical and applied chemistry.

Cyclopentacycloheptene

CAS: 275-51-4

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.
