Mesitylene CAS#108-67-8

Mesitylene is an aromatic hydrocarbon belonging to the xylene isomers. It is a clear, water-white liquid with a strong aromatic odor. Mesitylene has a relatively high boiling point of approximately 144.5 °C and is poorly soluble in water. It is commonly used as a solvent in various industrial applications, including the production of chemicals, pharmaceuticals, and as a component in gasoline. Due to its chemical stability and low reactivity, it is also utilized in the synthesis of dyes and as a dehydrating agent for organic compounds. Mesitylene’s chemical properties make it a versatile and valuable component in the chemical industry.
