(5-Cyclopropyl-2-methoxyphenyl)boronic acid is primarily used in organic synthesis, particularly in cross-coupling reactions like the Suzuki-Miyaura reaction. This reaction is widely employed in the pharmaceutical industry for the formation of carbon-carbon bonds, enabling the synthesis of complex organic molecules, including drug intermediates and active pharmaceutical ingredients (APIs). Its boronic acid group acts as a key reagent, facilitating the coupling of aryl or vinyl halides with aryl or vinyl boronic acids to produce biaryl or styrene derivatives. Additionally, it finds utility in material science for the development of organic electronic materials, such as polymers and small molecules used in OLEDs or organic photovoltaics. Its cyclopropyl and methoxy substituents contribute to its stability and reactivity, making it a versatile building block in various chemical transformations.
