Syringaldehyde is an organic compound that occurs in trace amounts widely in nature.
Scolytus multistriatus uses it as a signal to find a host tree during oviposition.
It is a colorless solid (impure samples appear yellowish) that is soluble in alcohol and polar organic solvents.
[citation needed] Syringaldehyde can be found naturally in the wood of spruce and maple trees.
[3] Syringaldehyde is also formed in oak barrels and extracted into whisky, which it gives spicy, smoky, hot and smoldering wood aromas.
