Product Description:

2-Benzothienylboronic acid is an organoboron compound featuring a benzothiophene core with a boronic acid functional group at the 2-position. Its molecular formula is C8H7BO2S, and it appears as a white to off-white crystalline powder. The compound is stable under standard storage conditions but is sensitive to air and moisture, requiring storage in a cool, dry place. This compound serves as a critical building block in organic synthesis, particularly in Suzuki-Miyaura cross-coupling reactions. It is widely utilized in medicinal chemistry for the synthesis of biologically active molecules, including potential kinase inhibitors, antiviral agents, and central nervous system (CNS) active compounds. The benzothiophene moiety is a privileged scaffold in drug discovery, often found in pharmaceuticals targeting inflammation, cancer, and neurological disorders. Additionally, it is employed in the development of organic electronic materials and agrochemical intermediates. Due to its boronic acid functionality, 2-Benzothienylboronic acid enables efficient carbon-carbon bond formation under mild conditions, making it a versatile reagent in both academic research and industrial process development. It is typically handled with standard laboratory safety precautions, avoiding inhalation or skin contact.
