Metabolite Identification
Common NameIsopropylbenzene
DescriptionIsopropylbenzene, also known as 2-phenylpropane or benzene, isopropyl, belongs to the class of organic compounds known as cumenes. These are aromatic compounds containing a prop-2-ylbenzene moiety. Isopropylbenzene is possibly neutral. Outside of the human body, Isopropylbenzene is found, on average, in the highest concentration within ceylon cinnamons and gingers. Isopropylbenzene has also been detected, but not quantified in, several different foods, such as celery stalks, cumins, herbs and spices, and sweet cherries. This could make isopropylbenzene a potential biomarker for the consumption of these foods. Gastric lavage, emesis, and the administration of activated charcoal should be avoided, as vomiting increases the risk of aspiration. Isopropylbenzene is formally rated as a possible carcinogen (by IARC 2B) and is also a potentially toxic compound. Treatment is mainly symptomatic and supportive. Volatile hydrocarbons are absorbed mainly through the lungs, and may also enter the body after ingestion via aspiration. Petroleum distillate poisoning may cause nausea, vomiting, cough, pulmonary irritation progressing to pulmonary edema, bloody sputum, and bronchial pneumonia. Petroleum distillates are also irritating to the skin. 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.
