Carbon tetrabromide formula graphical representation
Synonyms
Carbon bromide; Methane tetrabromide; Tetrabromomethane; [NIOSH] UN2516
Category
Brominated Solvents
Description
Colorless to yellow-brown crystals with a slight odor; [NIOSH]
Sources/Uses
Used in organic syntheses; [ACGIH]
Comments
In an acute study of mice, carbon tetrabromide was determined to be 2.2 times more toxic to the liver than carbon tetrachloride. It causes significant eye irritation (tearing) in workers even at lower exposure levels. [ACGIH] A lachrymator; [HSDB] Inhalation of high concentrations can cause CNS depression; Causes corrosive burns to eyes [ICSC]
