Syringaldehyde is an organic compound that occurs in trace amounts widely in nature. Some species of insects use syringaldehyde in their chemical communication systems. Scolytus multistriatus uses it as a signal to find a host tree during oviposition.
Because it contains many functional groups, it can be classified in many ways - aromatic, aldehyde, phenol. It is a colorless solid (impure samples appear yellowish) that is soluble in alcohol and polar organic solvents. Its refractive index is 1.53.
