COBr

COBr, also known as carbonyl bromide, is a chemical compound with the formula COBr2. It is a member of the carbonyl halide family, similar to phosgene (COCl2) and carbonyl fluoride (COF2). Carbonyl bromide is a colorless gas with a pungent odor. It is known to be a toxic substance, and its handling requires appropriate safety precautions.

The compound can be synthesized through various chemical reactions. One common method involves the reaction of carbon monoxide with bromine. Another route is the reaction of carbon tetrabromide with oxygen or carbon monoxide.

COBr is relatively unstable and can decompose, particularly when exposed to heat or moisture. It is a reactive compound and can undergo hydrolysis in the presence of water to form carbon dioxide and hydrogen bromide. Its reactivity also means it can participate in various organic synthesis reactions, acting as a brominating agent. Due to its toxicity and reactivity, COBr is not widely used in industrial applications and is primarily encountered in research laboratories.
