context_page_description: Guaiazulene, also azulon or 1,4-dimethyl-7-isopropylazulene, is a dark blue crystalline hydrocarbon. A structural isomer of azulene, guaiazulene is a bicyclic sesquiterpene that is a constituent of some essential oils, mainly oil of guaiac and chamomile oil, which also serve as its commercial sources. Various soft corals also contain guaiazulene as a principal pigment. Its low melting point makes guaiazulene difficult to handle, in contrast to the crystalline nature of the parent azulene. The electronic structure of guaiazulene and azulene are very similar.

caption: The blue color of the mushroom Lactarius indigo is due to the guaiazulene derivative (7-isopropenyl-4-methylazulen-1-yl)methyl stearate.[2]
