Quality Control

Our 3-Nitrosalicylaldehyde 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 spectroscopy, to ensure it meets exacting standards for research and industrial use. A detailed Certificate of Analysis (COA) with batch-specific results is provided to guarantee traceability and consistency.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at room temperature (15-25°C). Due to its light-sensitive nature and tendency to be easily oxidized, it is recommended to store the material under an inert atmosphere for long-term preservation and to minimize exposure to air upon opening.
