(2-Chloro-6-hydroxyphenyl)boronic acid is primarily used in organic synthesis and pharmaceutical research. It serves as a key intermediate in the preparation of various biologically active compounds, particularly in the development of drugs targeting specific enzymes or receptors. The boronic acid group in the compound makes it valuable for Suzuki-Miyaura cross-coupling reactions, a widely used method for forming carbon-carbon bonds in the synthesis of complex organic molecules. Additionally, its structure allows for potential applications in the design of sensors or probes for detecting specific analytes due to its ability to interact with diols and other functional groups. Its chlorinated and hydroxylated aromatic ring further enhances its utility in creating diverse chemical architectures for medicinal chemistry and material science applications.
