Quality Control

Our 4,4’-(1,5-Pentanediyl)Dioxydibenzaldehyde is manufactured under strict quality management systems. Every batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation via FT-IR and NMR, to ensure it meets exacting standards for research and industrial use. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with each shipment and is available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). Due to its sensitivity to oxidation, it is recommended to handle and store the material under an inert atmosphere (e.g., nitrogen or argon) for long-term stability. Keep away from strong oxidizing agents.
