Quality Control

Our 1,1-Diphenyl-2-Nitroethylene is produced under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation by FT-IR and NMR spectroscopy, to ensure it meets the high standards required for research and industrial synthesis. A detailed Certificate of Analysis (COA) is provided with every shipment, guaranteeing traceability, consistency, and reliability for your critical processes.

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 sensitivity to light and propensity for oxidation, it is recommended to store the material under an inert atmosphere (e.g., nitrogen or argon) for long-term stability. Keep away from heat, sparks, and open flames.
