Trimethylboroxin（Cat No.:R061803）is an organoboron compound with the molecular formula [(CH₃BO)₃], consisting of a six-membered boroxine ring formed by alternating boron and oxygen atoms, each boron bonded to a methyl group. It is a colorless, volatile liquid or low-melting solid and serves as a source of methylboronic acid or methylboron species in organic synthesis. Trimethylboroxin is used in Suzuki-Miyaura cross-coupling reactions, where it acts as a methylating agent for aryl halides. Its cyclic trimeric structure offers thermal stability, and it is valued for its efficiency in introducing methyl groups under mild reaction conditions.
