Quality Control

Our 8-Mercaptoquinoline Hydrochloride is produced under strict quality management protocols. Each batch undergoes rigorous analytical testing, including HPLC for purity, IR and NMR for structural confirmation, and loss on drying for moisture content. We ensure compliance with relevant industry standards, and a comprehensive Certificate of Analysis (COA) detailing all test results is provided with every shipment.

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). This material is hygroscopic (moisture-sensitive) and should be handled under an inert atmosphere when appropriate to prevent oxidation and moisture uptake.
