Quality Control

Every batch of 3-[(4-Carboxyphenyl)Amino]Propanoic Acid is produced under a strict quality management system. We employ advanced analytical techniques including HPLC, NMR, and FTIR to ensure identity, purity, and consistency meet the high standards required for fine chemical synthesis. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles 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 place at a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed after opening to minimize exposure to atmospheric moisture. Keep away from incompatible materials.
