Product Description:

3,4-Dimethoxyphenylboronic acid is an organoboron compound featuring a phenyl ring substituted with two methoxy groups at the 3- and 4-positions and a boronic acid functional group. It is a white to off-white crystalline powder commonly used as a key synthetic building block. Its primary application is in Suzuki-Miyaura cross-coupling reactions, a fundamental method for forming carbon-carbon bonds in organic synthesis. The boronic acid group readily couples with aryl or vinyl halides in the presence of a palladium catalyst. Due to the electron-donating methoxy substituents, this compound is particularly valuable for synthesizing more complex molecules with specific electronic properties. These properties make it a crucial intermediate in the research and development of organic electronic materials, such as those used in organic light-emitting diodes (OLEDs) and organic semiconductors. The compound should be stored in a cool, dry place, protected from moisture, as boronic acids can undergo dehydration to form boroxines. It is widely available from chemical suppliers for laboratory-scale synthesis and material science research.
