CAS 106-42-3: p-Xylene

Description: p-Xylene, also known as para-xylene, is an aromatic hydrocarbon with the chemical formula C8H10. It is one of the isomers of xylene, distinguished by the arrangement of its two methyl groups attached to a benzene ring in a para position. p-Xylene is a colorless, flammable liquid with a sweet odor, and it is insoluble in water but soluble in organic solvents. It has a relatively low boiling point and a moderate vapor pressure, making it volatile under standard conditions. p-Xylene is primarily used as an industrial solvent and as a precursor in the production of terephthalic acid, which is essential for manufacturing polyester fibers and resins. Additionally, it is utilized in the synthesis of various chemicals, including phthalic anhydride and other aromatic compounds. Due to its flammability and potential health effects upon inhalation or skin contact, proper safety measures should be observed when handling p-xylene in laboratory or industrial settings.
