Quality Control

Our 2,5-Diamino-3-Chloropyridine is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing, including HPLC, NMR, and GC-MS, to ensure identity, purity, and consistency. Certificates of Analysis (COA) documenting all critical parameters are available upon request, supporting your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at room temperature (15-25°C). Due to its light-sensitive nature and tendency to oxidize, it is recommended to handle under an inert atmosphere for long-term storage and to minimize headspace in opened containers.
