Beschreibung

Allgemeine Beschreibung

Bromoform is a major organic source for atmospheric reactive bromine BrO_x (Br+BrO)[1]. It is formed as a product of chlorination of drinking water[2]. It undergoes photodissociation to form the Br₂ fragment and mechanism has been investigated by cavity ring-down absorption spectroscopy[3].

Anwendung

Bromoform was used to evaluate the genotoxicity of chlorodibromomethane, bromodichloromethane and bromoform[2].
