Quality Control

Our H-Ala-Pna is manufactured under strict quality management systems. Every batch undergoes comprehensive analytical testing, including HPLC for purity, IR and NMR for structural confirmation, and tests for residual solvents and moisture content. We provide full traceability and Certificates of Analysis (COA) are available for all shipments, ensuring compliance with your research and production specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (typically 15-25°C). This product is hygroscopic (moisture-sensitive) and light-sensitive; therefore, containers must be kept tightly sealed in a dry environment and away from direct light exposure to maintain stability and purity.
