Description and Uses

2-Acetylthiophene(2AT) is used as an intermediate in the manufacturing of drugs like Tiamonium Iodide, Suprofan, Stepronin, Tenonitrozole, Namirotene, etc. 2AT is used as an important precursor to thiophene-2-acetic acid (T2AA) or its acid chloride (Cl) and thiophene-2-carboxylic acid (T2CA) (Cl). It is important that the process used to synthesize 2AT yields the lowest amount of 3- acetylthiophene isomer.
