Used primarily as an intermediate in the production of acetic acid, pyridine derivatives, and pentaerythritol. Commonly employed in the synthesis of perfumes, flavors, and dyes due to its reactive aldehyde group. Serves as a precursor in the manufacture of pharmaceuticals and agricultural chemicals. Also utilized in the preservation of fruits and fish products, and in some cases as a denaturant for alcohol. Plays a role in the production of resins and plastics when combined with other monomers.
