3505 3-Methyl-2-pentene 3-Methyl-2-pentene is an exogenous organic compound with the formula C6H12 and an average molecular weight of 84.16 g/mol. It exists as a liquid at room temperature. 3-Methyl-2-pentene belongs to the branched unsaturated hydrocarbons, a subclass of unsaturated hydrocarbons within the organic compounds. This hydrocarbon has been recorded as being found in or released from electrical and electronic equipment, specifically antennas. 922-62-3 643935 C6H12 84.093900 -134.8°C Oral (L400) ; inhalation (L400) ; dermal (L400) Petroleum distillates are central nervous system depressants and cause pulmonary damage. (A600) Volatile hydrocarbons are absorbed mainly through the lungs, and may also enter the body after ingestion via aspiration. (A600) 3-Methyl-2-pentene is found in gasoline, which is possibly carcinogenic to humans (Group 2B). (L135) 3-Methyl-2-pentene is a component of gasoline. 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. (A600, L1297) Petroleum distillate poisoning may cause nausea, vomiting, cough, pulmonary irritation progressing to pulmonary edema, bloody sputum, and bronchial pneumonia. At high amounts, central nervous system depression may also occur, with symptoms such as weakness, dizziness, slow and shallow respiration, unconsciousness, and convulsions. Petroleum distillates are also irritating to the skin. (A594) 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.
