For procurement managers navigating the complex landscape of chemical sourcing, identifying versatile and high-quality raw materials is paramount. Gallic Acid, with its CAS number 149-91-7, stands out as a prime example of such a compound, offering a broad spectrum of applications across various industries. As a leading manufacturer and supplier in China, we are dedicated to providing businesses with the essential chemical building blocks they need to innovate and thrive. Understanding the chemical and physical properties of Gallic Acid is the first step in leveraging its full potential.

Key Properties and Grades for Informed Purchasing

Gallic Acid presents as a white powder, possessing a density of approximately 1.7 g/cm³ and a melting point of 252 °C (with decomposition). Its molecular formula is C7H6O5, with a molecular weight of 170.120. We offer Gallic Acid in several grades, each tailored to specific industry requirements:

  • Industrial Grade: Typically assays ≥99%, suitable for general industrial applications like tanning or as a component in drilling fluid formulations.
  • Pharmaceutical Grade: Features a higher purity, often ≥99.5%, with strict controls on parameters like Loss on Drying (≤1%) and Residue on Ignition (≤0.1%), making it ideal for API synthesis and pharmaceutical formulations.
  • Food Grade: Also requiring ≥99.5% purity, this grade meets stringent regulations for use in food products, particularly for synthesizing food antioxidants.

When you buy Gallic Acid, understanding these specifications ensures you receive a product that meets your exact needs, whether for critical pharmaceutical research or large-scale industrial production. We provide transparent information on all our product specifications, enabling informed decisions for your procurement strategy.

The Wide-Ranging Applications of Gallic Acid

The true value of Gallic Acid lies in its extensive applicability:

  • Antioxidant Synthesis: Gallic acid esters, derived from Gallic Acid, are highly effective food antioxidants. By acting as a reducing agent, Gallic Acid itself and its derivatives can scavenge free radicals, protecting food products from oxidative degradation and extending shelf life. This makes it a sought-after ingredient for food manufacturers looking to enhance product quality and stability.
  • Pharmaceutical and Biological Activities: Gallic Acid is recognized for its remarkable biological properties, including anti-inflammatory, anti-bacterial, anti-viral, and anti-mutation effects. It can inhibit the growth of various microorganisms in vitro, making it a compound of interest for developing new therapeutic agents or as a component in healthcare products.
  • Historical Inks and Specialty Materials: Historically, Gallic Acid was a key component in the creation of blue-black iron-gall inks, valued for their permanence. Modern applications extend to its use as a UV absorber, a flame retardant, and a crucial material in semiconductor photoresist formulations.
