Quality Control

Our Benzoic Acid, 3,4-Dihydroxy-, Monosodium Salt is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing to ensure it meets high-purity standards suitable for pharmaceutical and food-grade applications. Certificates of Analysis (COA) detailing purity, identity, and impurity profiles are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed to prevent absorption of atmospheric moisture. For long-term storage, consider using an inert atmosphere to minimize potential oxidation.
