At ambient temperature bromine is a brownish-red liquid. It has a similarly coloured vapour with an offensive and suffocating odour. It is the only non-metallic element that is liquid under ordinary conditions, it evaporates easily at standard temperature and pressures in a red vapour that has a strong disagreeable odour resembling that of chlorine. Bromine is less active chemically than chlorine and fluorine but is more active than iodine; its compounds are similar to those of the other halogens. Bromine is soluble in organic solvents and in water.

Bromine is used in industry to make organobromo compounds. A major one was dibromoethane an agent for leaded gasoline, before they were largely phased out due to environmental considerations. Other organ bromines are used as insecticides, in fire extinguishers and to make pharmaceuticals. Bromine is used in making fumigants, dyes, flame proofing agents, water purification compounds, sanitizes, medicinal, agents for photography and in brominates vegetable oil, used as emulsifier in many citrus-flavoured soft drinks.
