Application: Widely used in perfumery, pesticide chemistry and organic synthesis industry, also used for large-scale synthesis of trimethoprim in the pharmaceutical industry. 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. |
