GHS Hazard Classification

Reported hazard statements	H301 (66.7%), H302 (33.3%), H311 (66.7%), H312 (33.3%), H315 (66.7%), H319 (66.7%), H331 (66.7%), H332 (33.3%)

Documented Uses

• Used as a research chemical; [HSDB]
• 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)
