Used in organic synthesis as a multifunctional building block for constructing complex polyphenolic frameworks. Its aldehyde and hydroxyl groups enable participation in condensation, cyclization, and metal-chelation reactions. Commonly employed in the development of conjugated organic materials for optoelectronic applications, such as organic semiconductors and sensors. Also investigated for use in crosslinking polymers to enhance thermal and mechanical stability. Shows potential in medicinal chemistry due to structural similarity to bioactive polyphenols, supporting research in antioxidants and enzyme inhibitors.
