Quality Control

Our 1,4-Benzenedicarboxaldehyde, Monooxime, [C(E)]- (9Ci) is produced under a strict quality management system. Every batch undergoes comprehensive analytical testing, including HPLC, NMR, and FTIR, to ensure identity, purity, and consistency. A detailed Certificate of Analysis (COA) is provided with each shipment, documenting all critical quality parameters. We are committed to meeting the stringent requirements of research and development applications.

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 light and propensity for oxidation, it is recommended to store the material under an inert atmosphere (e.g., nitrogen or argon) for long-term stability. Keep away from heat, sparks, and open flame.
