text: # Orsellinaldehyde
  
  Orsellinaldehyde is a dihydroxybenzaldehyde with a methyl side group. It can be classified as a resorcinol, benzaldehyde or toluene derivative. It is a natural product of several fungi. Fungi that contain it include Grifola frondosa, Aspergillus cleistominutus, Aspergillus nidulans, and Agrocybe praecox.
  
  ## Production
  
  Orsellinaldehyde can be produced by a Gattermann reaction of orcinol, using zinc cyanide under a hydrogen chloride atmosphere, which adds an aldimine (-CH=NH) group to the ring, followed by hydrolysis to give the aldehyde.
  
  ## Properties
  
  The melting point is between 181 and 183 °C.
