Quality Control

Our 4-Cyanobenzaldehyde is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation by FT-IR and NMR spectroscopy, to ensure it meets the high standards required for fine chemical synthesis. Certificates of Analysis (COA) detailing all specifications are provided with every shipment to guarantee traceability and batch-to-batch 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 property of being easily oxidized, it is recommended to store the material under an inert atmosphere (e.g., nitrogen or argon) for long-term preservation. Keep away from heat, sparks, open flames, and strong oxidizing agents.
