Quality Control

Our 3-Pyridinecarboxaldehyde, 5-Ethyl-2-Methyl- (9Ci) is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC and GC analysis, to ensure high purity and consistency. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with every shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) in a cool, dry, and well-ventilated place. Recommended storage temperature is 2-8°C for long-term stability. Keep away from heat, sparks, and open flames. This material is easily oxidized; ensure containers are properly sealed after each use to minimize exposure to air.
