Quality Control

Our n-Methyl-4-(p-Formylstyryl)Pyridinium Methosulfate is produced under stringent quality management protocols. Each batch undergoes comprehensive analytical testing, including HPLC for purity, NMR for structural confirmation, and Karl Fischer titration for moisture content, to ensure it meets exacting research and production standards. A detailed Certificate of Analysis (COA) is provided with every shipment to guarantee traceability and consistent batch-to-batch quality.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its light-sensitive and easily oxidized nature, it is recommended to handle under an inert atmosphere for long-term storage and to minimize exposure to air and moisture.
