Metabolite Identification
Common Name3,3-Dimethylhexane
Description3,3-Dimethylhexane belongs to the class of organic compounds known as branched alkanes. These are acyclic branched hydrocarbons having the general formula CnH2n+2. 3,3-Dimethylhexane is possibly neutral. 3,3-Dimethylhexane has been detected, but not quantified, in herbs and spices and tea. 3,3-Dimethylhexane is a potentially toxic compound. Volatile hydrocarbons are absorbed mainly through the lungs, and may also enter the body after ingestion via aspiration. Treatment is mainly symptomatic and supportive. Gastric lavage, emesis, and the administration of activated charcoal should be avoided, as vomiting increases the risk of aspiration. 3,3-Dimethylhexane is present in petroleum distillates. Petroleum distillates are also irritating to the skin. Petroleum distillate poisoning may cause nausea, vomiting, cough, pulmonary irritation progressing to pulmonary edema, bloody sputum, and bronchial pneumonia. 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.
