Phenylboronic acid neopentylglycol ester is widely used in organic synthesis, particularly in Suzuki-Miyaura cross-coupling reactions. It serves as a stable and efficient boron reagent for forming carbon-carbon bonds, enabling the synthesis of complex organic molecules, including pharmaceuticals and agrochemicals. Its stability and solubility in organic solvents make it a preferred choice for catalytic processes. Additionally, it is employed in the preparation of functional materials, such as polymers and sensors, due to its ability to interact with diols and other Lewis bases. Its role in medicinal chemistry is notable for creating bioactive compounds and drug intermediates.
