Quality Control

Our (S)-Isobutyl 2-Aminopropanoate HCl is manufactured under strict quality management systems. Each batch is subjected to rigorous analytical testing, including chiral purity verification by HPLC, to ensure it meets the high standards required for pharmaceutical R&D and other critical applications. A comprehensive Certificate of Analysis (COA) detailing identity, purity, chiral excess, and impurity profiles is provided with every shipment.

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 prevent moisture absorption, which can compromise product stability and performance. Keep away from incompatible materials.
