Guaiazulene also azulon or 14-dimethyl-7-isopropylazulene is a dark blue crystalline hydrocarbon. A derivative 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.
