Quality Control

We maintain a strict quality management system to ensure batch-to-batch consistency and high purity for research and development applications. Our products undergo rigorous quality testing, including advanced chromatographic and spectroscopic methods, to ensure compliance with customer specifications. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with each 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 (typically 15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed in a dry environment to prevent degradation. For long-term storage, consider using desiccants.
