This haloalkane, also known as alpha,beta-dibromoethane, presents as a colorless, sweet-smelling liquid. Store in a dry and well-ventilated place. Containers which are opened must be carefully resealed and kept upright to prevent leakage. This substance may darken on storage at ambient temperatures, as it is light sensitive. 1,2-Dibromoethane is incompatible with alkali metals, oxidizing agents, and magnesium.
