Quality Control

Our 3-(4-Formyl-Phenoxymethyl)-4-Methoxy-Benzaldehyde is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation by FT-IR and NMR, to ensure it meets the high standards required for research and industrial synthesis. Certificates of Analysis (COA) documenting all critical quality attributes are available upon request to support your regulatory and quality assurance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at a controlled room temperature (15-25°C). Due to its sensitivity to oxidation, it is recommended to handle and store the material under an inert atmosphere for long-term stability. Keep away from heat, sparks, and open flame.
