Used primarily as an intermediate in organic synthesis, especially in the pharmaceutical and agrochemical industries. It serves as a building block for constructing more complex thiophene derivatives, which are valuable in the development of bioactive molecules. Its reactivity allows for easy introduction into larger conjugated systems, making it useful in the synthesis of organic semiconductors and electronic materials. Commonly employed in coupling reactions and acylation processes to form amides, esters, and ketones that are key in drug discovery and material science.
