1-Ethyl-3-methylbenzene

Description:
1-Ethyl-3-methylbenzene, also known as pseudocumene, is an aromatic hydrocarbon with the molecular formula C10H12. It features a benzene ring substituted with an ethyl group and a methyl group at the 1 and 3 positions, respectively. This compound is a colorless liquid at room temperature, exhibiting a characteristic sweet odor. It is insoluble in water but soluble in organic solvents, making it useful in various industrial applications. Pseudocumene is primarily utilized as a solvent and as an intermediate in the production of other chemicals, including resins and plastics. Its boiling point is relatively high compared to aliphatic hydrocarbons, and it has a moderate vapor pressure. Additionally, 1-ethyl-3-methylbenzene is flammable and should be handled with care to avoid inhalation or skin contact. Safety data sheets recommend using appropriate personal protective equipment when working with this substance, as it may pose health risks upon prolonged exposure.
