properties

Iodoethane is a colorless, volatile, flammable liquid with an ethereal odor that is sparingly soluble in water. It has a dynamic viscosity of 0.556 mPa · s at 25 ° C. Upon contact with light, iodoethane turns red and slowly decomposes in water. The technical product contains silver , ethanol or copper as a stabilizer.

use

Iodoethane is used as a heavy liquid for mineral analysis and for organic synthesis.

safety instructions

The vapors of iodoethane can form explosive mixtures with air when the substance is heated above its flash point.
