Quality Control

Our H-Ala-Ala-Gln-Oh is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity, chiral analysis for stereochemical integrity, and comprehensive identification tests. We provide full traceability and Certificates of Analysis (COA) are available for all shipments, detailing purity, residual solvents, and other critical parameters to ensure compliance with your research or production standards.

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 material is hygroscopic (moisture-sensitive) and must be kept under dry, inert conditions to maintain stability and purity. For long-term storage, consider desiccated environments.
