      Product Detail  


    Product Description

    Gallic Acid is a naturally occurring polyphenolic compound widely found in plants, fruits, and teas. It is known for its strong antioxidant properties and versatile applications in pharmaceuticals, food, cosmetics, and chemical industries.
    Produced by hydrolysis of tannins or extracted from plant sources, Gallic Acid serves as an important intermediate, antioxidant, and analytical reagent in both industrial and laboratory settings.


    Key Applications

    1. Pharmaceutical Industry

    • Used as an intermediate in the synthesis of trimethoprim, gallic esters, and other bioactive compounds.

    • Exhibits antioxidant, antibacterial, anti-inflammatory, and antiviral properties.

    • Commonly applied in health supplements and drug formulations for free radical scavenging and anti-aging effects.

    2. Food and Beverage Industry

    • Acts as a natural antioxidant and preservative to prevent oxidation and rancidity in food products.

    • Used as a quality control marker for tea, wine, and plant-based extracts.

    • Can be utilized in flavor and color stabilization of beverages and processed foods.

    3. Cosmetics and Personal Care

    • Employed in skin care formulations for its antioxidant and anti-inflammatory benefits.

    • Helps protect skin cells from oxidative stress and may assist in anti-aging and whitening applications.

    • Often incorporated in lotions, serums, and sunscreens.

    4. Chemical and Industrial Applications

    • Used as a raw material for the manufacture of pyrogallol and inks.

    • Serves as a complexing agent and reagent in analytical chemistry.

    • Applied in metal ion chelation and antioxidant coatings.

    5. Research and Laboratory Use

    • Utilized as a standard reference compound in polyphenol and tannin quantification.

    • Plays a key role in biochemical and antioxidant activity studies.

    Air and Water Reactions:

    Reactive Group:

    Acids, Carboxylic

    Reactivity Profile:

    Phenols, such as GALLIC ACID, do not behave as organic alcohols, as one might guess from the presence of a hydroxyl (-OH) group in their structure. Instead, they react as weak organic acids. Phenols and cresols are much weaker as acids than common carboxylic acids (phenol has pKa = 9.88). These materials are incompatible with strong reducing substances such as hydrides, nitrides, alkali metals, and sulfides. Flammable gas (H2) is often generated, and the heat of the reaction may ignite the gas. Heat is also generated by the acid-base reaction between phenols and bases. Such heating may initiate polymerization of the organic compound. Phenols are sulfonated very readily (for example, by concentrated sulfuric acid at room temperature). The reactions generate heat. Phenols are also nitrated very rapidly, even by dilute nitric acid.
