Cc1ccccc1

Cc1ccccc1 is the SMILES notation for toluene, also known as methylbenzene. It is a simple aromatic hydrocarbon consisting of a benzene ring with a single methyl substituent. Its molecular formula is C7H8 and the IUPAC name is methylbenzene.

Toluene is a colorless, volatile liquid with a characteristic sweet odor. It is flammable and has a boiling point of 110.6°C and a melting point of -95°C. The liquid’s density is about 0.867 g/cm3 at 20°C, and it is soluble in most organic solvents while only sparingly soluble in water. Toluene is relatively stable under standard conditions but can form hazardous vapors when heated or subjected to flames.

Production and occurrence: Most industrial toluene is produced as a byproduct of catalytic reforming and other petroleum refining processes. It is a component of some crude oils and is also obtained from the processing of natural gas liquids. In addition to industrial production, trace amounts can be found in the environment from petroleum-related activities and combustion processes.

Applications: Toluene serves as a versatile solvent in paints, coatings, adhesives, inks, and rubber cements. It is also used as a feedstock in the synthesis of various chemicals, including benzoic acid, benzaldehyde, and some dyes and polymers. It is a constituent of gasoline and is used in the production of certain energetic materials.

Safety and regulation: Toluene is a flammable hazardous substance. Exposure can affect the nervous system and cause dizziness or drowsiness; prolonged or high-level exposure poses greater health risks. It is regulated in occupational and environmental contexts to limit inhalation and dermal exposure.
