5-Chloro-2-methoxyphenylboronic acid is a specialized organoboron intermediate used in Suzuki-Miyaura cross-coupling reactions. Its molecular formula is C7H8BClO2 with CAS No. 140966-24-5. High-purity synthesis typically involves lithiation of 2-chloroanisole followed by reaction with trimethyl borate.
Store under inert atmosphere at 2-8°C to prevent hydrolysis. Use appropriate PPE including gloves and eye protection; avoid inhalation of dust or skin contact due to potential irritancy.
