Quality Control

Our Benzoic Acid, 3,5-Diamino-2-Hydroxy-4-Methyl-, Methyl Ester is manufactured under strict quality management systems. Every batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation via IR and NMR spectroscopy, to ensure it meets the high standards required for sensitive synthesis applications. A comprehensive Certificate of Analysis (COA) detailing all specifications is provided with each shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, 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 the risk of oxidation.
