Wholesale 3-Methylthiophene CAS:616-44-4 Factory, Exporter

Product Introduction

3-Methylthiophene has typical properties of thiophene compounds, and its five-membered heterocyclic structure has certain aromaticity. The presence of methyl groups will affect the distribution of electron clouds on the ring, thereby affecting its chemical reactivity. For example, under appropriate conditions, substitution reactions can occur, the hydrogen atoms on the methyl groups can be replaced by other groups, and electrophilic substitution reactions can also occur on the thiophene ring, such as halogenation, nitration, sulfonation and other reactions.
