PRODUCT INTRODUCTION
description
Ethyl bromide appears as a colorless volatile liquid. Slightly soluble in water and denser than water. Flash point below 0 °F. Vapors are heavier than air. Toxic by inhalation. Irritates skin and eyes. Used to make pharmaceuticals and as a solvent.
Description
Bromoethane has been used as an ethylating agent in organic synthesis and gasoline, as a refrigerant and as an extraction solvent; it has had limited use as a local anaesthetic.
