Exposure limits TLV-TWA skin 5 ppm (15.5 mg/m3) (ACGIH), 25 ppm (77.5 mg/m3) (OSHA).
Stability Stable, but contact with air may lead to the formation of explosive peroxides. A peroxide test should be carried out before this material is used if it has been exposed to air for some time, especially if it is to be purified by distillation. Contact with strong oxidizing agents may cause fire or explosion. Incompatible with strong bases, ac
