Quality Control

Our Pyridine, 3-Ethoxy-4,5-Dimethoxy-, 1-Oxide (9Ci) is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity and spectroscopic identification (NMR, IR), to ensure it meets the stringent requirements for research and process development. We provide a detailed Certificate of Analysis (COA) with every shipment, documenting all critical quality attributes. Specifications can be aligned with cGMP standards for pharmaceutical applications upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept sealed to prevent absorption of atmospheric moisture, which could affect purity and stability.
