Quality Control

Our 3,4-Dihydro-1,5-Naphthyridin-2(1H)-One is manufactured under a strict quality management system. Every batch undergoes rigorous analytical testing, including HPLC, NMR, and mass spectrometry, to ensure identity, purity, and consistency. Certificates of Analysis (COA) documenting all critical parameters are available upon request, supporting your compliance and R&D needs.

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 (moisture-sensitive) nature, the container must be kept tightly sealed after opening to minimize exposure to atmospheric humidity.
