GENERAL DESCRIPTION & EXTERNAL LINKS

Triazole is one of a class of organic heterocyclic compounds containing a five-membered diunsaturated ring structure composed of three nitrogen atoms and two carbon atoms at nonadjacent positions. The simplest member of the Triazole family is triazole itself, white to pale yellow crystalline solids with a weak characteristic odor; soluble in water and alcohol, melts at 120 C, boils at 260 C. Triazole and its derivatives are used for biological activities such as antiviral, antibacterial, antifungal and antituberculous. 1,2,4-Triazole is used as an intermediate for phytosanitary, pharmaceutical, medicine and pesticide products, photoconductor, and copying systems
