Quality Control

Our 5-(4-Carboxybenzylamino)Isophthalic Acid is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing to ensure identity, purity, and consistency, meeting the high standards required for research and industrial synthesis. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with every shipment and is 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 sealed to minimize exposure to atmospheric humidity. For long-term storage, consider using desiccants.
