Identification
Common Name1-Bromobutane
ClassSmall Molecule
Description1-Bromobutane is a colorless liquid that is insoluble in water, but soluble in ethanol and diethyl ether. As a primary haloalkane, it is especially prone to SN2 type reactions. It is commonly used as an alkylating agent, or in combination with magnesium metal in dry ether (Grignard reagent) to form carbon-carbon bonds. It can be used as a cleaning agent, an agent for chemical synthesis or as a solvent for extractions. It is highly flammable.

Toxicity Profile
Route of ExposureOral (9) ; inhalation (9) ; dermal (9)
Mechanism of Toxicity1-bromobutane reacts quickly with hepatic glutathione (GSH) leading to its rapid depletion. This can cause liver damage and has been shown to increase serum levels of alanine aminotransferase and aspartate aminotransferase. Hepatic contents of thiobarbituric acid reactive substances can also be significantly increased. Splenic GSH levels can also be significantly reduced by single treatment with 1-bromobutane. S-Butyl GSH conjugates were detected in spleen from 6 hr after treatment. Oral 1-bromobutane significantly suppressed the antibody response to a T-dependent antigen and the production of splenic intracellular interlukin-2.
MetabolismRabbits and rats dosed with 1-bromobutane excrete in urine, in addition to butylmercapturic acid, (2-hydroxybutyl)mercapturic acid, (3-hydroxybutyl)mercapturic acid and 3-(butylthio)lactic acid. In the rabbit about 14% and in the rat about 22% of the dose of 1-bromobutane is excreted in the form of the hydroxymercapturic acids. 1-bromobutane also forms glutathione conjugates. Three kinds of GSH conjugates, including S-butyl GSH, S-butyl cysteine, and (hydroxybutyl)mercapturic acid, have been identified in mice livers after oral dosing with 375-1500 mg/kg of the compound.
Toxicity ValuesLD50: 2761 mg/kg (Oral Rat) (4) LC50: 237 g/m3 over 30 minutes (Inhalation, Rat) (5)
Lethal DoseNot Available
Carcinogenicity (IARC Classification)No indication of carcinogenicity to humans (not listed by IARC).
Uses/SourcesNot Available
Minimum Risk LevelNot Available
Health EffectsHepatoxic, immunotoxic when ingested orally. Can cause lung damage and mucous membranes over extended periods/chronic exposures. Can cause skin and eye irritation. Not a carcinogen nor a mutagen nor a teratogen.
SymptomsSkin irritation if contacts skin, redness and itching of skin and eyes. Acute exposure may lead to coughing, shortness of breath, headache, nausea, vomiting
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.

General Function:
Temperature-gated cation channel activity
Specific Function:
Receptor-activated non-selective cation channel involved in detection of pain and possibly also in cold perception and inner ear function (PubMed:25389312, PubMed:25855297). Has a central role in the pain response to endogenous inflammatory mediators and to a diverse array of volatile irritants, such as mustard oil, cinnamaldehyde, garlic and acrolein, an irritant from tears gas and vehicule exhaust fumes (PubMed:25389312, PubMed:20547126). Is also activated by menthol (in vitro)(PubMed:25389312). Acts also as a ionotropic cannabinoid receptor by being activated by delta(9)-tetrahydrocannabinol (THC), the psychoactive component of marijuana (PubMed:25389312). May be a component for the mechanosensitive transduction channel of hair cells in inner ear, thereby participating in the perception of sounds. Probably operated by a phosphatidylinositol second messenger system (By similarity).
