Quality Control

Our Benzaldehyde, 3-Chloro-2-Fluoro-4-Methyl- is manufactured under strict quality management systems. Every batch undergoes rigorous analytical testing, including HPLC, GC, NMR, and IR spectroscopy, to ensure high purity and batch-to-batch consistency. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with each shipment to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at a controlled room temperature (15-25°C). This material is light-sensitive and easily oxidized; for long-term storage, consider maintaining under an inert atmosphere (e.g., nitrogen or argon) to preserve stability.
