CAS 526-73-8: 1,2,3-Trimethylbenzene

Description: 1,2,3-Trimethylbenzene, also known as pseudocumene, is an aromatic hydrocarbon with the molecular formula C9H12. It features a benzene ring with three methyl groups attached at the 1, 2, and 3 positions, resulting in a colorless liquid at room temperature. This compound has a characteristic sweet odor and is insoluble in water but soluble in organic solvents. Its boiling point is relatively high compared to non-aromatic hydrocarbons, reflecting its stable aromatic structure. 1,2,3-Trimethylbenzene is primarily used as a solvent and in the production of various chemicals, including resins and plastics. It is also a component in some fuel formulations. While it is considered to have low acute toxicity, prolonged exposure may lead to health concerns, including respiratory irritation and central nervous system effects. As with many aromatic compounds, it is important to handle 1,2,3-trimethylbenzene with care, following appropriate safety guidelines to minimize exposure.
