Quality Control

Our Biotin-Peg2-Hydrazide is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation, to ensure it meets the high standards required for research and commercial applications. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store at -20°C or below under desiccant. This product is hygroscopic (moisture-sensitive) and should be handled under inert atmosphere or in a controlled, dry environment to prevent degradation. Allow the vial to warm to room temperature in a desiccator before opening to minimize moisture uptake.
