Metabolite Identification
Common Name2-Methylheptane
Description2-Methylheptane belongs to the class of organic compounds known as branched alkanes. These are acyclic branched hydrocarbons having the general formula CnH2n+2. Thus, 2-methylheptane 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. 2-Methylheptane is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral. Octanes may be found in gasoline. Outside of the human body, 2-Methylheptane has been detected, but not quantified in, black elderberries. This could make 2-methylheptane a potential biomarker for the consumption of these foods. 2-Methylheptane is a potentially toxic compound. Petroleum distillates are also irritating to the skin. Volatile hydrocarbons are absorbed mainly through the lungs, and may also enter the body after ingestion via aspiration. Petroleum distillates are aspiration hazards and may cause pulmonary damage, central nervous system depression, and cardiac effects such as cardiac arrhythmias. They may also affect the blood, immune system, liver, and kidney. At high amounts, central nervous system depression may also occur, with symptoms such as weakness, dizziness, slow and shallow respiration, unconsciousness, and convulsions. 2-Methylheptane is a hydrocarbon and one of the isomers of octane. Petroleum distillate poisoning may cause nausea, vomiting, cough, pulmonary irritation progressing to pulmonary edema, bloody sputum, and bronchial pneumonia.
