Xylene, often referred to in its plural form "xylenes," encompasses a group of three isomers: ortho-xylene, meta-xylene, and para-xylene. These are colorless, flammable liquids derived from petroleum and are primarily used as solvents in the printing, rubber, and leather industries, as well as in the production of various chemicals. Xylenes are also present in gasoline and are used in the manufacturing of products like plastics and fibers. Due to their potential health effects, exposure to xylenes should be managed carefully in industrial settings.
