Quality Control

Our 3-(3-Formyl-Phenoxymethyl)-4-Methoxy-Benzaldehyde is manufactured under a strict quality management system. Every batch undergoes comprehensive analytical testing including HPLC, GC, NMR, and mass spectrometry to ensure identity, purity, and consistency. Certificates of Analysis (COA) detailing all specifications are provided and available upon request 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 place at room temperature (15-25°C). Due to its sensitivity to oxidation, it is recommended to store under an inert atmosphere (e.g., nitrogen) for long-term preservation. Keep away from heat, sparks, and open flame.
