[0002] Veratrone is a synthetic fragrance with the chemical name 3,4-dimethoxyphenylpropiotone. It is an important pharmaceutical intermediate and the main raw material for neurological drugs, with a wide range of uses.

[0003] Veratrone is synthesized with veratraldehyde as the main raw material. It is first carboxylated with methyl 2-chloropropionate under the catalysis of sodium methoxide, then hydrolyzed under alkaline conditions, decarboxylated with hydrochloric acid, and finally distilled to obtain the product.
