Hazard Information | Back Directory | [General Description]
White liquid with a strong skunk-like odor. | [Reactivity Profile]
ISOPROPYL MERCAPTAN(75-33-2) is 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. May liberate hydrogen sulfide when mixed with an acid. | [Air & Water Reactions]
Highly flammable. Soluble in water. | [Hazard]
Highly flammable, dangerous fire hazard. | [Health Hazard]
Inhalation causes loss of sense of smell, muscular weakness, convulsions, respiratory paralysis. Ingestion causes nausea and vomiting. Contact with eyes or skin causes irritation. | [Chemical Properties]
liquid with an exceedingly unpleasant smell | [Occurrence]
