Quality Control

Our 4-Pyridinecarboxaldehyde, 2-Chloro-5-Nitro- is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC, NMR, and GC-MS, to ensure identity, purity, and consistency. Certificates of Analysis (COA) are provided with every shipment, detailing all relevant specifications. We support cGMP compliance for pharmaceutical applications and can tailor purity grades to meet specific project requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at a controlled room temperature (15-25°C). This material is light-sensitive (store away from light) and easily oxidized (store under inert atmosphere). Keep away from heat, sparks, and open flame. For long-term storage, consider storage under an inert atmosphere such as nitrogen or argon.
