Quality Control

Our 4-Amino-3,5-dihydroxybenzoic acid is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation via IR and NMR spectroscopy, to ensure it meets high-purity standards suitable for research and synthesis. A Certificate of Analysis (COA) detailing all specifications is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). Due to its light-sensitive nature and tendency to be easily oxidized, prolonged exposure to light, air, or elevated temperatures should be avoided to maintain product integrity.
