Quality Control

Our Dihydrate CAS NO 42208-37-7 is produced under a strict quality management system. Each batch undergoes comprehensive analytical testing to ensure it meets the required specifications for identity, purity, and hydration state. Certificates of Analysis (COA) documenting results for key parameters such as assay, water content (by Karl Fischer), and related substances are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Due to its hygroscopic (moisture-sensitive) nature, the container must be kept in a cool, dry place. For long-term stability, store at a controlled room temperature (typically 15-25°C) in a low-humidity environment. Avoid temperature extremes and exposure to moisture.
