Quality Control

Our Pyrazinoyl Chloride, 3-Hydroxy- (6Ci) is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing, including HPLC, NMR, and FTIR, to ensure identity, purity, and conformity to established specifications. A Certificate of Analysis (COA) detailing all test results is provided with every shipment. We adhere to cGMP principles where applicable to support its use in regulated synthesis pathways.

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 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.
