Tetrazole Chemical Properties,Uses,Production

Description

Tetrazole is a class of synthetic organic heterocyclic compound containing a 5-member ring of four nitrogen atoms and one carbon atom. It appears as an odorless white to light-yellow crystalline powder. It has several pharmaceutical applications. Tetrazole compound can act as a bioisotere for the carboxylate group, angiotensin II receptor blockers such as losartan and candesartan as well as dimethyl thiazolyl diphenyl tetrazolium bromide (MTT), which can be used in MTT assay for quantifying the respiratory activity of liver cells. It can also be used in DNA assays. In addition, Tetrazole derivatives have also been used in explosives such as TNT or high performance solid rocket propellant formulations. Tetrazole can be synthesized through the reaction between anhydrous hydrazoic acid and hydrogen cyanide under pressure.

Chemical Properties

white crystals or crystalline powder

Uses

A catalyst for phosphoramidite synthesis.

Definition

ChEBI: A tetrazole tautomer where the proton is located on the 1st position.

General Description

Tetrazole is an odorless white to light-yellow crystalline powder. Mp:1 55-157°C. When heated to decomposition Tetrazole emits toxic oxides of nitrogen fumes. Can explode if exposed to shock or heat from friction or fire. The primary hazard is from blast effect where the entire load can explode instantaneously and not from flying projectiles and fragments.

Health Hazard

Fire may produce irritating, corrosive and/or toxic gases.

Fire Hazard

MAY EXPLODE AND THROW FRAGMENTS 1600 meters (1 MILE) OR MORE IF FIRE REACHES CARGO.
