Quality Control

Our Isoquinoline-5,8-Diamine is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity, residual solvent analysis, and identity confirmation via FT-IR and NMR spectroscopy. We provide a Certificate of Analysis (COA) with every shipment, detailing all specifications and test results. Our quality commitment ensures the material meets the stringent requirements for research and commercial synthesis applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at a controlled room temperature (15-25°C). Due to its sensitivity to light and oxidation, it is recommended to store the material under an inert atmosphere (e.g., nitrogen or argon) for long-term preservation. Keep away from heat, sparks, open flames, and incompatible materials.
