Quality Control

Our 2-Hydroxy-4-Amino Butanoic Acid is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including chiral purity assessment, to ensure it meets the stringent requirements for advanced synthetic applications. A detailed Certificate of Analysis (COA) is provided with every shipment, confirming identity, purity, and conformity to agreed specifications.

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 nature, the container must be kept tightly sealed after opening to prevent moisture absorption, which can affect stability and handling properties. Keep away from incompatible materials.
