Quality Control

Our 4-(2,3-Difluorophenyl)Benzaldehyde is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing including HPLC, GC, NMR, and FTIR to ensure identity, purity, and consistency. A detailed Certificate of Analysis (COA) is provided with every shipment, confirming compliance with customer specifications and industry standards for fine chemical intermediates.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) at a controlled room temperature (15-25°C) in a cool, dry, and well-ventilated place. This material is easily oxidized and should be kept away from strong oxidizing agents. Keep the container tightly sealed when not in use to minimize exposure to air and moisture.
