(2-Chloro-5-cyano-3-methylphenyl)boronic acid

(2-Chloro-5-cyano-3-methylphenyl)boronic acid, identified by CAS 2225178-62-9 and molecular formula C8H7BClNO2, is a functionalized arylboronic acid. This compound features a phenyl ring substituted with a chlorine atom, a cyano group, a methyl group, and a boronic acid moiety. It serves as a versatile building block in synthetic organic chemistry, particularly valuable in Suzuki-Miyaura cross-coupling reactions for the formation of new carbon-carbon bonds. Its distinct functional groups make it an important intermediate for the synthesis of complex organic molecules, including potential pharmaceutical intermediates and agrochemicals, exclusively for research and development applications.

• Handle with appropriate personal protective equipment (PPE), including chemical-resistant gloves, safety glasses or goggles, and a lab coat. Ensure use in a well-ventilated area or a chemical fume hood to prevent inhalation. Avoid direct contact with skin and eyes. In case of exposure, rinse affected areas immediately with plenty of water and seek medical attention if irritation persists. Store the compound in a cool, dry place, away from incompatible materials. Always refer to the Safety Data Sheet (SDS) for comprehensive safety guidelines prior to handling.
