Beschreibung

Allgemeine Beschreibung

Mesitylene is a methyl-substituted benzene hydrocarbon, a specialty solvent used for research and industrial applications. Derivatives of mesitylene are used as colorant precursors to prepare organic dye intermediates such as 2,4,6-trimethylaniline.[1]

Anwendung

• Mesitylene is used as a:
• building block to manufacture antioxidants, plasticizers, rubber, adhesives, etc.[2]
• ligand in organometallic reactions[3][4]
• developer for photo patternable silicones[5]
• precursor to prepare a variety of fine chemicals[5]
