2-Bromo-4-methylthiophene（Cat No.:L038223）is a halogenated heteroaromatic compound consisting of a thiophene ring substituted with a bromine atom at the 2-position and a methyl group at the 4-position. This compound is a valuable intermediate in organic synthesis, particularly in cross-coupling reactions such as Suzuki, Stille, and Heck couplings, where the bromine acts as a reactive site for further functionalization. The electron-rich thiophene ring and the steric influence of the methyl group make it useful in constructing conjugated systems, pharmaceutical agents, and organic electronic materials like OLEDs and conductive polymers.
