Regulatory informationChemical: Hexane, 1-bromo-Hexane, 1-bromo- is listed on the EPA's Chemical Data Reporting (CDR) system. Manufacturers and importers of Hexane, 1-bromo- are required to report information about their production and use of this chemical to the EPA under the Toxic Substances Control Act (TSCA). (40 eCFR Part 711)Status: Active Update: 09-09-2021 https://echa.europa.eu/registration-dossier/-/registered-dossier/108291-Bromohexane: Does not have an individual approval but may be used under an appropriate group standard
Hazards summaryA skin and mucous membrane irritant[Alfa Aesar MSDS] See 1-Bromopropane and 2-Bromopentane.
Hazard Classes and CategoriesFlam. Liq. 3 (99.5%)
Protective Action Criteria (PAC)120 [mg/m3]1300 [mg/m3]7600 [mg/m3]
TreatmentEYES: irrigate opened eyes for several minutes under running water. INGESTION: do not induce vomiting. Rinse mouth with water (never give anything by mouth to an unconscious person). Seek immediate medical advice. SKIN: should be treated immediately by rinsing the affected parts in cold running water for at least 15 minutes, followed by thorough washing with soap and water. If necessary, the person should shower and change contaminated clothing and shoes, and then must seek medical attention. INHALATION: supply fresh air. If required provide artificial respiration.
Health effectsBromine vapour causes irritation and direct damage to the mucous membranes. Elemental bromine also burns the skin. The bromide ion is a central nervous system depressant and chronic exposure produces neuronal effects. This is called bromism and can result in central reactions reaching from somnolence to coma, cachexia, exicosis, loss of reflexes or pathologic reflexes, clonic seizures, tremor, ataxia, loss of neural sensitivity, paresis, papillar edema of the eyes, abnormal speech, cerebral edema, delirium, aggressiveness, and psychoses. (L625, L626, L627)
Adverse effectsNeurotoxin - Acute solvent syndrome
Exposure routesOral (L626)inhalation (L626)dermal (L626)
Toxicity summaryBromine is a powerful oxidizing agent and is able to release oxygen free radicals from the water in mucous membranes. These free radicals are also potent oxidizers and produce tissue damage. In additon, the formation of hydrobromic and bromic acids will result in secondary irritation. The bromide ion is also known to affect the central nervous system, causing bromism. This is believed to be a result of bromide ions substituting for chloride ions in the in actions of neurotransmitters and transport systems, thus affecting numerous synaptic processes. (L626, L627, A543)
Signs and SymptomsBromine vapour causes irritation and direct damage to the mucous membranes. Symptoms include lacrimation, rhinorrhoea, eye irritation with mucous secretions from the oropharyngeal and upper airways, coughing, dyspnoea, choking, wheezing, epistaxis, and headache. The bromide ion is a central nervous system depressant producing ataxia, slurred speech, tremor, nausea, vomiting, lethargy, dizziness, visual disturbances, unsteadiness, headaches, impaired memory and concentration, disorientation and hallucinations. This is called bromism. (L626, L627)
Carcinogen ClassificationNo indication of carcinogenicity to humans (not listed by IARC).
Toxicity DataLC50 (rat) = 550,000 mg/m3/30min
