Quality Control

Our Pyrimidine, 4-Ethynyl-2-Methoxy- (9Ci) is produced under strict quality management protocols. Each batch undergoes rigorous analytical testing to ensure identity, purity, and consistency. Certificates of Analysis (COA) detailing specifications such as assay (by HPLC), identity (by IR and/or NMR), and impurity profiles are available for every shipment. We are committed to meeting the stringent requirements of research and development applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at controlled room temperature (typically 15-25°C). Keep away from heat, sparks, and open flame. Due to its light-sensitive nature, containers should be kept in opaque or amber glass, or stored in dark conditions.
