Documented Uses

• Used as an intermediate to make dyestuff, drugs, and cyclopropane; Also used as a herbicide; [HSDB]
• Intermediate for dyestuff and pharmaceutical industries, cyclopropane manufacture.
• Used as a herbicide /SRP65: Former use/
• Prepared by the action of hydrobromic acid on trimethylene glycil in the presence of sulfuric acid
• From trimethylene glycol and PBr3
• Bromine is mainly absorbed via inhalation, but may also enter the body through dermal contact. Bromine salts can be ingested. Due to its reactivity, bromine quickly forms bromide and may be deposited in the tissues, displacing other halogens. (L626)
