Description of 1-methylethyl
- 1-methylethyl, also azulon or 1,4-dimethyl-7-isopropylazulene, is a dark blue crystalline hydrocarbon. A derivative of azulene, 1-methylethyl 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 1-methylethyl as a principal pigment. Its low melting point makes 1-methylethyl difficult to handle, in contrast to the crystalline nature of the parent azulene. The electronic structure (and colors) of 1-methylethyl and azulene are very similar.
The blue color of the mushroom Lactarius indigo is due to the 1-methylethyl derivative (7-isopropenyl-4-methylazulen-1-yl)methyl stearate.

What’s the application of Guaiazulene ?
- Blue crystalline or viscous liquid. Turns from blue to green and finally to yellow when exposed to light. Insoluble in water, insoluble in ethanol, soluble in chloroform, ether, vegetable oil, and volatile oil. Guaiacol has anti-inflammatory and promotes the regeneration of tissue granulation, can promote the healing of burns and scald wounds, and has the effect of preventing heat, radiation, and chaps. It is used for the treatment of burns, scalds, chaps, frostbite, eczema, dermatitis, and the prevention of high heat radiation.
