This review imparts a survey on the synthesis and reactions of ethylidenethiosemicarbazides as well as their biological activities during the period from 2005 to 2015. The synthetic utilities of ethylidenethiosemicarbazides, as building blocks, for the synthesis of various heterocyclic compounds such as azoles, azines, and fused ring systems, have been demonstrated.
