Packaging & Storage
Proper packaging and storage are essential to maintain the high purity and stability of gallic acid.
- Packaging
Our gallic acid is available in multiple packaging options to accommodate different production scales and requirements. Standard packaging consists of 25 kilograms per fiber drum, with a double-layer food-grade PE bag inside to protect the product from moisture and contamination. The drum is sealed to ensure product integrity during transport and storage. Custom packaging options are also available upon request, including smaller quantities such as 1 kilogram, 5 kilograms, or 10 kilograms in aluminum foil bags for R&D and sample purposes. All packaging materials are food-grade and designed to protect the product from light, moisture, and physical damage.
- Storage Conditions
To preserve product quality and extend shelf life, gallic acid should be stored in a cool, dry, well-ventilated area, protected from light and moisture. The recommended storage temperature is below 25°C, with relative humidity maintained under 60% to prevent caking and degradation. Containers should remain tightly sealed when not in use to avoid moisture ingress and contamination.
- Shelf Life
When stored under the recommended conditions, gallic acid has a shelf life of 24 months from the date of manufacture. After opening, we recommend using the product within 6 months to ensure optimal purity. The product should be re-sealed immediately after each use to prevent moisture absorption and maintain product integrity.
- Handling Precautions
Gallic acid is sensitive to moisture and should be handled with care. We recommend using clean, dry utensils when handling the product and avoiding prolonged exposure to light and heat. For bulk storage, implementing a first-in-first-out (FIFO) inventory system is advised to ensure product freshness. Before use, the product should be inspected for any visible changes in appearance, colour, or odor. If any deviation from the original specifications is observed, we recommend contacting our quality assurance team for guidance before proceeding with use. Samples are available for stability testing upon request.
Application
Gallic acid (purity ≥ 99%) is a high-purity organic acid that serves as a key intermediate across multiple industrial sectors, including pharmaceutical synthesis, antioxidant production, and specialty chemicals. In the pharmaceutical industry, it is used as a key intermediate in the synthesis of antibacterial agents, antiviral drugs, and cardiovascular pharmaceuticals, where its high purity and controlled impurity profile ensure consistent performance in sensitive synthesis processes. In antioxidant production, gallic acid is the primary precursor for the synthesis of gallate esters such as propyl gallate and octyl gallate, which are widely used to prevent lipid oxidation in food, cosmetic, and industrial products. Additionally, gallic acid is used in the synthesis of chemical intermediates like trimethoxybenzoic acid, in the formulation of photosensitive materials, and as a reference standard in laboratory research and analytical testing. Its high purity (≥ 99%) and compliance with USP/EP standards make it suitable for demanding fine chemical and high-end applications where raw material consistency is critical.
