Common Name | p-Xylene |

Description | p-Xylene, also known as p-methyltoluene or para-xylene, belongs to the class of organic compounds known as p-xylenes. These are aromatic compounds that contain a p-xylene moiety, which is a monocyclic benzene carrying exactly two methyl groups at the 1- and 4-positions. p-Xylene is possibly neutral. Outside of the human body, p-Xylene is found, on average, in the highest concentration within black walnuts. p-Xylene has also been detected, but not quantified in, several different foods, such as parsley, green bell peppers, pepper (c. frutescens), cauliflowers, and yellow bell peppers. This could make p-xylene a potential biomarker for the consumption of these foods. The p stands for para, identifying the location of the methyl groups as across from one another. p-Xylene is a potentially toxic compound. For skin contact, the skin should be washed with soap and water. When there is expression of muscarinic overstimulation due to excess acetylcholine at muscarinic acetylcholine receptors symptoms of visual disturbances, tightness in chest, wheezing due to bronchoconstriction, increased bronchial secretions, increased salivation, lacrimation, sweating, peristalsis, and urination can occur. |
