Application

Guaiazulene can be used as a starting material for the synthesis of:
  • Azulene-based dye molecules such as 3-(7-isopropyl-1,4-dimethylazulen-3-yl)-2-cyanoacrylic acid and 5-(7-isopropyl-1,4-dimethylazulen-3-yl)-2-cyanopenta-2,4-dienoic acid.
  • Stilbazulenyl nitrone, a second-generation azulenyl nitrone which can be used as a chain-breaking antioxidant.
  • Bis-azulenyl based near-infrared fluorescence quencher.

Three pigments of the guaiazulene class have been isolated from the gorgonian Calicogorgia granulosa. Structures of these compounds have been determined as guaiazulene, 2,2'- diguaiazulenylmethane, and a new compound, 2,2'-biguaiazulenyl, by combined chemical and spectroscopic methods. 2,2'-Biguaiazulenyl exhibited moderate antimicrobial
