What is N-(2-Methylphenyl)thiourea?
General Description
Crystalline solid.
Reactivity Profile
When heated to decomposition, N-(2-Methylphenyl)thiourea emits very toxic fumes of oxides of nitrogen and sulfur. [EPA, 1998]. Organosulfides are incompatible with acids, diazo and azo compounds, halocarbons, isocyanates, aldehydes, alkali metals, nitrides, hydrides, and other strong reducing agents. Reactions with these materials generate heat and in many cases hydrogen gas. Many of these compounds may liberate hydrogen sulfide upon decomposition or reaction with an acid.
Health Hazard
The material is highly toxic if orally ingested.
Fire Hazard
When heated to decomposition, N-(2-Methylphenyl)thiourea emits very toxic fumes of oxides of nitrogen and sulfur.
