Quality Control

Every batch of 5-Amino-2-(Carboxymethyl)Benzoic Acid is produced and tested under a strict quality management system. We ensure compliance with relevant industry standards for fine chemicals and pharmaceutical intermediates. Comprehensive testing includes identity confirmation, purity assay, and impurity profiling. A Certificate of Analysis (COA) detailing all test results is provided with each 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 tightly sealed after opening to prevent absorption of atmospheric moisture, which can affect product stability and performance.
