Density  0.725 g/mL at 25 °C(lit.)
vapor density  3.5 (vs air)
vapor pressure  120 mm Hg ( 20 °C)
refractive index  n20/D 1.367(lit.)
Flash point −29 °F
storage temp.  Store below +30°C.
solubility  3.11g/l
form  Liquid
color  APHA: ≤25
Relative polarity 2.2
Odor Sweet, slightly sharp; characteristic pungent; ethereal; like amphor and ethyl ether.
explosive limit 1-21%, 100°F
Water Solubility  9 g/L (20 ºC)
Merck  14,5212
BRN  1731256
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
