Quality Control

Our 5-Hydrazino-Isophthalic Acid is manufactured under a strict quality management system. Every batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation, to ensure it meets exacting standards for research and industrial use. A Certificate of Analysis (COA) detailing batch-specific results is provided with each shipment to guarantee traceability and consistency.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent degradation. For long-term storage, consider using an inert atmosphere to minimize oxidation.
