What is 3-Acetylthiophene?
Chemical properties
white to light yellow crystal powder
The Uses of 3-Acetylthiophene
3-Acetylthiophene was used in the preparation of 1-(methylthiophenylidine)-8-naphthylamine(Schiff′s base) and 1-(thiophen-3-yl)ethanone.
Definition
ChEBI: 3-Acetylthiophene is an aromatic ketone.
General Description
3-Acetylthiophene modified glassy carbon electrode has been used in voltammetric determination of uric acid in urine samples.
Purification Methods
Recrystallise the thiophene from pet ether (b 30-60o) or EtOH. The 2,4-dinitrophenylhydrazone crystallises from CHCl3, m 265o, and the semicarbazone crystallises from EtOH, m 174-175o. [Campaigne & Le Suer J Am Chem Soc 70 1555 1948, Beilstein 17/9 V 399.]
