Quality Control

Our Pyridine, 2-(Cyclopropylethynyl)- (9Ci) is produced under strict quality management systems. Every batch undergoes comprehensive analytical testing, including HPLC, GC, NMR, and mass spectrometry, to ensure identity, purity, and consistency. Certificates of Analysis (COA) documenting all critical parameters are available upon request, supporting your regulatory and R&D documentation needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at a controlled room temperature (typically 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.
