Henry's Law Constant :2.57 at 25 °C (headspace-GC, Arp and Schmidt, 2004)
Exposure limits :TLV-TWA 1045 mg/m³ (250 ppm) (ACGIH), 2090 mg/m³ (500 ppm) (OSHA); STEL 1300 mg/m³ (310 ppm) (ACGIH).
Dielectric constant :3.9（25℃）
Stability :Extremely flammable. This material is a serious fire and explosion risk. Vapour may travel considerable distances to an ignition source, which need not be an open flame, but may be a hot plate, steam pipe, etc. Vapour may be ignited by the static electricty which can build up when isopropyl ether is being poured from one vessel
