Common Name | Pentane |
---|
Description | Pentane, also known as CH3-[CH2]3-CH3 or R-601, belongs to the class of organic compounds known as alkanes. These are acyclic branched or unbranched hydrocarbons having the general formula CnH2n+2 , and therefore consisting entirely of hydrogen atoms and saturated carbon atoms. Thus, pentane is considered to be a hydrocarbon lipid molecule. Gastric lavage, emesis, and the administration of activated charcoal should be avoided, as vomiting increases the risk of aspiration. Pentane is a very hydrophobic molecule, practically insoluble in water, and relatively neutral. Pentane is an alkane tasting compound. Pentane is found, on average, in the highest concentration within kohlrabis. Pentane has also been detected, but not quantified, in a few different foods, such as alcoholic beverages, celery stalks, and soy beans. This could make pentane a potential biomarker for the consumption of these foods. Pentane is a potentially toxic compound. The main metabolite is 2-pentanol, followed by 3-pentanol, and 2-pentanone. It affects the peripheral nervous system through demyelinization and axonal degeneration. Pentane is a central nervous system depressant and can cause anorexia, euphoria, dizziness, headache, depression, confusion, inability to concentrate, anoxia, narcosis, and loss of consciousness and coma at high concentrations. Ingestion may cause pulmonary toxicity due to pentane aspiration, including chemical pneumonitis, acute lung injury, and hemorrhage. Pentane is absorbed following inhalation and ingestion, and to a small extent from dermal exposure. |
