01 · Identification
What Bromoethene is
Bromoethene is gas under normal atmospheric conditions, colorless liquid under pressure with a characteristic pungent odor. Its molecular formula is C2H3Br and its molecular weight is 106.95 g/mol. It boils at 15.8 °C, melts at -138 °C, is soluble in water.
Under the GHS it carries the signal word Danger. It is classed as hazardous Air Pollutants (HAPs).
