Quality Control

Our Pyridine, 4-Ethyl-2-Ethynyl- (9Ci) is produced under stringent quality management protocols. Each batch undergoes comprehensive analytical testing, including HPLC, GC, NMR, and FTIR analysis, to ensure identity, purity, and consistency. We provide a detailed Certificate of Analysis (COA) with every shipment, documenting all critical quality parameters. Our commitment to traceability and reliability supports demanding applications in research and scale-up development.

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 hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation. Keep away from heat, sparks, and open flame.
