Ethylboronic acid

Ethylboronic acid (CAS: 4433-63-0) is a simple and high-activity aliphatic boronic acid fine chemical intermediate. It appears as white to pale yellow crystalline solid at room temperature, with stable physical and chemical properties in low-temperature sealed and dry environments. The molecular structure contains active boronic acid functional groups, which can efficiently participate in Suzuki-Miyaura coupling reactions and various organic derivatization reactions. It features moderate water solubility and excellent reaction activity, widely applied in pharmaceutical intermediate synthesis, functional material preparation and laboratory organic synthesis research.
