Exposure limits
TLV-TWA 50 mg/m3 (20 ppm) (ACGIH), 240 mg/m3 (100 ppm) (OSHA); IDLH 2000 ppm.
Stability:
Stable. Incompatible with acids, bases, oxidizing agents, copper, copper alloys, brass, bronze, iron, metal chlorides, peroxides and a wide variety of other materials. Reacts with compounds containing labile hydrogen. Extremely flammable - note low boiling point, low flash point and very wide explosion limits. Moisture sensitive.
