Reaktivität anzeigen
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.
Brandgefahr
When heated to decomposition, 1,4-PHENYLENE DIISOTHIOCYANATE emits very toxic fumes of nitrogen oxides and sulfur oxides.
Sicherheitsprofil
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
mögliche Exposition
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.
