In organic chemistry, the largest families of organic compounds belong in the heterocyclic compounds.In our daily life, the importance of heterocyclic compounds is very essential.It has a broad range of applications in medicinal chemistry.Benzotriazole is a bicyclic heterocyclic system consisting of three nitrogen atoms and a fused benzene ring, shows wide range of biological and pharmacological activities.Benzotriazole has been a matter of discussion among the scientific community due to its potential characteristics and touched areas such as medicinal, pharmacological, industrial, etc. Benzotriazole derivatives have shown several pharmacological activities, which are antimicrobial activity, anti-inflammatory, analgesic activity, anticancer, antifungal, antibacterial, anticancer, anthelmintic, antidepressant, antioxidative, antitubercular, antiviral, anticorrosive, plant growth inhibitor, anti-inflammatory, etc. INTRODUCTION: Benzotriazole is coming from benzo-fused azoles are a class of heterocyclic compounds of great interest in the pharmaceutical and medicinal chemistry area.Benzotriazole has great characteristics in the context of electrondonating nature, group release, anion director in surrounding, etc. Benzotriazole is easy to introduce into molecules by a variety of addition, condensation, and substitution reactions.Benzotriazole comprises two fused rings; its fivemembered rings can show tautomerism.
