Protocatechuic Acid (PCA), scientifically known as 3,4-Dihydroxybenzoic acid, is a fascinating compound that bridges the gap between natural products and high-value chemical applications. Understanding its chemical structure is key to appreciating its diverse biological activities and its utility as a pharmaceutical intermediate and functional ingredient.

PCA belongs to the family of phenolic acids, characterized by a benzene ring with a carboxyl group and two hydroxyl groups. Specifically, it is a dihydroxybenzoic acid, with hydroxyl groups situated at the 3 and 4 positions of the benzoic acid ring. This particular arrangement of functional groups is crucial for its potent antioxidant properties, as the hydroxyl groups can readily donate hydrogen atoms to neutralize free radicals.

The chemical formula of Protocatechuic Acid is C7H6O4, and its molar mass is approximately 154.12 g/mol. Its CAS number, 99-50-3, serves as a unique identifier in chemical databases worldwide. The presence of both a carboxyl group and phenolic hydroxyls imparts a certain polarity and reactivity to the molecule, enabling it to participate in various chemical reactions and biological interactions.

The benefits derived from this structure are extensive. As a natural polyphenol antioxidant, PCA's ability to scavenge free radicals is well-documented. This antioxidant activity is fundamental to its anti-inflammatory effects and its potential protective roles against various diseases, including those related to oxidative stress and chronic inflammation. For those looking to buy Protocatechuic Acid, understanding these structural-activity relationships helps in appreciating its value.

Moreover, its role as a protocatechuic acid pharmaceutical intermediate stems from its adaptable structure, allowing for modifications and conjugations to create more complex drug molecules. Whether for its direct therapeutic potential or as a building block for advanced pharmaceuticals, the chemical identity of PCA underscores its importance. At NINGBO INNO PHARMCHEM CO.,LTD., we ensure that the PCA we supply meets the stringent purity standards required for these critical applications.
