Applications

Bromoform is widely used as a solvent for waxes, oils and greases. It is utilized for mineral ore separation in geological tests. It is used as an intermediate in chemical synthesis as well as a laboratory reagent. It is the ingredient of fire-resistant chemicals and fluid gauges. It acts as a sedative and as cough reducing agent.

Notes

Light-sensitive. A lachrymator. Incompatible with chemically active metals and strong bases.
