Description and Uses
3-Methylthiophene is found in coffee and coffee products. it is a maillard product, present in roast coffee aroma.
3-Methylthiophene is a member of thiophenes. Conducting polymer precursor. Copolymerization of 3-alkylthiophene and 3-methylthiophene is a promising approach to provide a polymer which has both solution processible property and high electrical conductivity.
