Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the production of compounds with potential therapeutic effects. It is often employed in the development of drugs targeting the central nervous system, such as antipsychotics and antidepressants. Additionally, it serves as a building block in organic synthesis for creating complex molecules with specific biological activities. Its reactivity as an acyl chloride makes it valuable for introducing the (3,4-dimethoxyphenyl)acetyl group into various chemical structures, enhancing their pharmacological properties.
