Quality Control

Our (Z)-4-Hydrazino-4-Oxo-2-Butenoic Acid Sodium Salt is manufactured under strict quality management protocols. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation, to ensure it meets the high standards required for research and process chemistry. Certificates of Analysis (COA) detailing batch-specific results are available upon request to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent oxidation and moisture absorption. Keep away from incompatible materials.
