Product Overview
Gallic Acid, chemically known as 3,4,5-trihydroxybenzoic acid, is a naturally occurring organic trihydroxybenzoic acid found in various plants and hydrolyzable tannins. As a critical chemical building block, it serves as a fundamental intermediate in the synthesis of numerous pharmaceutical compounds, antioxidants, and industrial materials. Our facility produces high-quality Gallic Acid adhering to strict international standards, ensuring consistency for downstream chemical synthesis and formulation processes.
This compound is characterized by its distinct phenolic structure, which imparts significant reactivity suitable for esterification and other organic transformations. Whether utilized in the production of propyl gallate for food preservation or as a key reagent in analytical chemistry, our Gallic Acid provides the reliability required for large-scale industrial operations.

Industrial Applications
The versatility of Gallic Acid makes it indispensable across several sectors. Primarily, it acts as a precursor for synthesizing gallic acid esters, such as propyl gallate and octyl gallate, which are widely recognized as effective antioxidants in food and cosmetic formulations. These derivatives help prevent oxidation and extend the shelf life of various products.
In the chemical industry, Gallic Acid is utilized in the manufacture of blue-black inks, where it reacts with iron salts to form stable precipitates. It also serves as a valuable component in tanning processes, flame retardants, and semiconductor photoresist materials. Additionally, it is employed in the production of water-based drilling mud fluidizers, offering performance comparable to lignosulfonates. While historically noted for biological activities in research contexts, our supply is focused on its role as a robust chemical intermediate for further synthesis and industrial formulation.
