Quality Control

Our 2,5-Diaminopyridine is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing, including HPLC for purity, residual solvent analysis, and identity confirmation via FT-IR and NMR, to ensure it meets the high standards required for synthetic applications. Certificates of Analysis (COA) with detailed chromatograms and spectral data are provided for traceability and regulatory support.

Storage

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