Applicazioni

Veratraldehyde was used in the preparation of 4-chloromethyl-2-(dimethoxyphenyl)-1,3-dioxolane. It was used in the synthesis of (+)-lithospermic acid, having anti-HIV activity. It forms 1:1 inclusion complexes with cyclodextrins. It reacts with 3-acetyl-2,5-dimethythiophene to yield chalcone dye, (2E)-3-(3,4-Dimethoxyphenyl)-1-(2,5-dimethylthiophen-3-yl)prop-2-en-1-one.

Note

Air sensitive. Incompatible with oxidizing agents.
