2-Amino-3-o-chlorobenzoyl-5-ethylthiophene can be used as the raw material for the synthesis of Etizolam, which is an important sedative hypnotic and antidepressant drug. Its derivative, 2-amino-3-(p-chlorobenzoyl) thiophene scaffold has been widely employed as a pharmacophore for the identification of small molecules acting as allosteric modulators at the adenosine A1 receptor.
