1H-1,2,4-Triazole-3,5-diamine Chemical Properties,Uses,Production

Chemical Properties

colourless crystals or faintly yellow powder

Uses

Inhibitor of DNA synthesis.

Definition

ChEBI: An aromatic amine that is 1,2,4-triazole substituted at positions 3 and 5 by amino groups.

General Description

Colorless crystals.

Air & Water Reactions

1H-1,2,4-Triazole-3,5-diamine is sensitive to air. Dust can be explosive when suspended in air at specific concentrations. Water soluble.

Reactivity Profile

The triazoles, of which 1H-1,2,4-Triazole-3,5-diamine is a member, are a group of highly explosive materials that are sensitive to heat, friction, and impact. Sensitivity varies with the type of substitution to the triazole ring. The amine substituted derivatives, 1H-1,2,4-Triazole-3,5-diamine, tend not to be explosion sensitive. Metal chelated and halogen substitution of the triazol ring make for a particularly heat sensitive material. Azido and nitro derivatives have been employed as high explosives. No matter the derivative these materials should be treated as explosives. 1H-1,2,4-Triazole-3,5-diamine forms salts readily with acids.

Health Hazard

SYMPTOMS: 1H-1,2,4-Triazole-3,5-diamine is stable under normal laboratory conditions.

Fire Hazard

Flash point data for 1H-1,2,4-Triazole-3,5-diamine are not available. 1H-1,2,4-Triazole-3,5-diamine is probably combustible.

Safety Profile

Human systemic effects by intravenous route: leukopenia (reduced white blood cell count) and thrombo cytopenia (reduced blood platelet count). Human mutation data reported. Questionable carcinogen with experimental tumorigenic data. When heated to decomposition it emits toxic fumes of NOx.

Purification Methods

The triazole crystallises from water or EtOH. [Beilstein 26 III/IV 1161.]
