Product Description:

3-Methoxyphenylboronic acid is an organoboron compound featuring a boronic acid group attached to a methoxy-substituted phenyl ring. It is a white to off-white crystalline solid, stable under normal conditions, and widely used as a key building block in organic synthesis. Its primary application is in Suzuki-Miyaura cross-coupling reactions, where it serves as a boronic acid partner to form carbon-carbon bonds with aryl or vinyl halides, enabling the construction of biaryl structures. This makes it essential for synthesizing pharmaceuticals, agrochemicals, and advanced materials. In medicinal chemistry, it is frequently employed as a small-molecule fragment for drug discovery, particularly in the development of kinase inhibitors and other bioactive compounds. Additionally, 3-methoxyphenylboronic acid can be utilized in the preparation of boronate esters and as a precursor for functionalized arenes. It is typically handled with standard laboratory precautions due to its mild irritant properties.
