Gallic acid (MF: C₇H₆O₅ MW: 170.12), also known as gallic acid, with the chemical name 3,4,5-trihydroxybenzoic acid, is a naturally occurring polyphenolic organic acid. It is widely present in plants such as gallnuts, tea leaves, and grape seeds, exhibiting both antioxidant, antibacterial, anti-inflammatory, and other biological and chemical activities. It serves as a key raw material for synthesizing gallic acid ester derivatives.
