2-Furanboronic acid(CAT: M061858) is a heteroaromatic boronic acid featuring a furan ring substituted at the 2-position with a boronic acid group. With the molecular formula C₄H₅BO₃, it serves as a versatile building block in organic synthesis, particularly in Suzuki–Miyaura cross-coupling reactions for forming C–C bonds with aryl or vinyl partners. Its heteroaryl structure imparts unique electronic and steric properties, enabling the preparation of biologically active molecules, functional materials, and fine chemicals. 2-Furanboronic acid is valuable in medicinal chemistry, agrochemical research, and material science for developing complex heterocycles, drug candidates, and conjugated systems with tailored properties.
