Chemical Properties

Those engaged in the manufacture, formulation and application of this anthelmintic compound. Incompatibilities: In general, keep away from strong oxidizers, moisture, strong acids, strong bases. This is a thiocyanate compound. Violent reactions may occur upon contact with chlorates (potassium chlorate, sodium chlorate), nitrates, nitric acid; organic peroxides.

Uses

Reagent for solid-phase sequencing.

Uses

anthelmintic

General Description

Odorless colorless crystals. Melting point 132°C.

Reactivity Profile

1,4-PHENYLENE DIISOTHIOCYANATE reacts readily with amines [Noller]. These reactions may generate significant amounts of heat . Emits very toxic fumes of nitrogen oxides and sulfur oxides when heated to decomposition [EPA, 1998].

Health Hazard

1,4-PHENYLENE DIISOTHIOCYANATE is highly toxic if ingested. It is a central nervous system and gastrointestinal toxin in humans.

Fire Hazard

When heated to decomposition, 1,4-PHENYLENE DIISOTHIOCYANATE emits very toxic fumes of nitrogen oxides and sulfur oxides.

Safety Profile

Poison by ingestion and intraperitoneal routes. Human systemic effects by ingestion: hallucinations, nausea. When heated to decomposition it emits very toxic fumes of NOx,CN,and SOx.See also THIOCYANATES

Potential Exposure
