Quality Control

Our L-Alanine, L-Alanyl-, Conjugate Monoacid, Pentahydrate is produced under strict quality management systems. Each batch undergoes rigorous analytical testing, including chiral purity verification and impurity profiling by HPLC, to ensure it meets the high standards required for pharmaceutical and research applications. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and specific tests is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). This compound is hygroscopic (moisture-sensitive); therefore, the container must be kept tightly sealed in a dry environment to prevent absorption of moisture and potential hydrate form changes.
