M-xylene, also known as meta-xylene, is an organic compound with the chemical formula C8H10. It is one of the three isomers of xylene, the other two being o-xylene (ortho-xylene) and p-xylene (para-xylene). M-xylene is a colorless, flammable liquid with a sweet, aromatic odor. It is a component of crude oil and is produced commercially through the refining of petroleum and by coal tar distillation.

M-xylene is primarily used as a solvent and as a feedstock for the production of other chemicals. Its main application is in the synthesis of isophthalic acid, which is used to produce polyesters, alkyd resins, and other polymers. It is also used in the production of insecticides and dyes. In its pure form, m-xylene finds use as a solvent in paints, varnishes, and printing inks, as well as in laboratory settings for various chemical reactions.

The isomers of xylene, including m-xylene, are often found together in mixtures, and their separation can be achieved through distillation or adsorption processes. M-xylene has a boiling point of approximately 139.1 °C (282.4 °F) and a melting point of approximately -47.87 °C (-54.17 °F). It is sparingly soluble in water but miscible with most organic solvents. Exposure to m-xylene can cause irritation to the eyes, skin, and respiratory tract, and prolonged or excessive exposure may affect the central nervous system.
