气味 (Odor)：Ethanethiol has a strongly disagreeable odor that humans can detect in minute concentrations. The threshold for human detection is as low as one part in 2.8 billion parts of air. Its odor resembles that of leeks, onions or cooked cabbage, but is quite distinct. Ethanethiol is intentionally added to butane and propane (see： LPG) to impart an easily noticed smell to these normally odorless fuels that pose the threat of fire, explosion, and asphyxiation.
气味 (Odor)：Strong chunk; offensive garlic.
嗅觉阈值(Odor Threshold)：0.0000087ppm
爆炸极限值(explosive limit)：2.8-18%(V)
水溶解性：Soluble in alcohol, ether, waterMiscible with alcohol, petroleum naphtha, acetone, dilute alkali and ether. Slightly miscible with water.

BRN：773638
Henry's Law Constant：3.57(x 10-3 atm?m3/mol) at 25 °C (Przyjazny et al., 1983)
暴露限值：TLV-TWA 0.5 ppm (～1.3 mg/m3 ) (ACGIH and MSHA); ceiling 10 ppm (OSHA); IDLH 2500 ppm (NIOSH).
稳定性：Stable. Extremely flammable - note low flash point. Incompatible with oxidizing agents, strong acids. May form explosive mixtures with air.
