Used primarily as an intermediate in organic synthesis, especially in the pharmaceutical industry. It plays a key role in the preparation of vasodilator drugs such as naftidrofuryl, which is used to treat peripheral vascular disorders. The compound’s acyl chloride group allows it to readily form esters and amides, making it valuable for constructing complex molecules. It is also employed in the synthesis of fragrances and specialty polymers due to its aromatic and ester-forming properties. Its reactivity requires careful handling under anhydrous conditions to avoid hydrolysis.
