GENERAL DESCRIPTION & APPLICATIONS
Tetrazole is one of a class of organic heterocyclic compounds containing a five-membered diunsaturated ring structure composed of four nitrogen atoms and one carbon atom. The simplest member of the tetrazole family is tetrazole itself, white to pale yellow crystalline solids with a weak characteristic odor; soluble in water and alcohol, melts at 156 C. Tetrazole is explosive. It is used as a gas generating agent for air bags. Shipment of tetrazole is available only as a solution in some countries. Tetrazole and its derivatives are used for biological activities such as antiviral, antibacterial, antifungal and antituberculous. They are used as catalysts in the synthesis of phosphonates.

Tetrazole is the traditional oligonucleotide synthesis activato for good coupling efficiency and to decrease the coupling times. But there are disadvantages of tetrazole; crystallisation problem from solution and potential explosive property at room temperature. Some alternatives have been recommended;

  • 5-Ethylthio-1H-tetrazole [CAS RN: 89797-68-2]
  • 5-Methylthio-1H-tetrazole [CAS RN: 29515-99-9]
  • 5-Benzylthio-1H-tetrazole [CAS RN: 21871-47-6]
  • 5-Nitrophenyl-1H-tetrazole
  • 4,5-Dicyanoimidazole [CAS RN: 1122-28-7]
