Formazans are compounds which contain the characteristic chain of atoms (−N=N-C=N-NH-) having wide range of applications in organic, inorganic and pharmaceutical chemistry and can be synthesized using different methods. Formazans have been found to possess wide spectrum of biological activities such as antiviral, antimicrobial, antiinflammatory, antifungal, anticacer, anti HIV. Several formazans show promising antifertility and anticonvulsant activity. This article is an attempt to discuss chemistry, methods of synthesis, biological and medicinal properties of formazan along with focus on some recent works in the field of formazans.
