Quality Control

Our β-(Isoxazolin-5-On-4-Yl)Alanine is produced under a strict quality management system. Each batch undergoes rigorous analytical testing, including HPLC for purity and chiral purity assessment, to ensure it meets the high standards required for research and development. A comprehensive Certificate of Analysis (COA) detailing identity, purity, 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 (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent degradation from atmospheric moisture.
