Chemical compound

2-Acetylthiophene is an organosulfur compound with the formula CH3C(O)C4H3S. A yellow liquid, it is the more useful of the two isomers of acetylthiophene. It is of commercial interest as a precursor to both thiophene-2-carboxylic acid and thiophene-2-acetic acid.[2] It is prepared by the reaction of thiophene with acetyl chloride in the presence of stannic chloride.[3]
