Quality Control

Our 3,5-Diiodo-4-Hydroxybenzhydrazide is manufactured under a strict quality management system. Every batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation via FT-IR and NMR, to ensure it meets the stringent requirements of our global clientele. Certificates of Analysis (COA) detailing all specifications are provided and available upon request to support your quality assurance and regulatory compliance needs.

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 light-sensitive and easily oxidized nature, it is recommended to store the material under an inert atmosphere (e.g., nitrogen or argon) for long-term stability. Keep away from strong oxidizing agents.
