Quality Control

Every batch of 2,3-Diamino-4,5-Dichloropyridine is manufactured under a strict quality management system. We provide comprehensive analytical documentation to ensure product integrity and traceability. Certificates of Analysis (COA) detailing purity, identity, and impurity profiles are available for all shipments. Our standard grade typically meets a purity specification of ≥97% (by HPLC), with custom purities available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed to prevent moisture absorption, which can affect product stability and performance.
