This book contains complete information on herecyclic compound "Benzimidazole". You can get information on chemistry, synthesis, and biological activity of the molecule. Readers are beneficial on adopting the synthesis methods which gives maximum yield whereas some methods of synthesis results in minimum yield which can be avoided during your research project. It will be helpful for researchers to modify the molecule for getting potent compounds. One of the synthesized compound which contains Beta-lactam ring fused with benzimidazole showed anti-bacterial activity. That compound can be compare with other commercial anti-bacterial compounds. `
