Quality Control

Our 1,7-Dichloroisoquinolin-4-Ol is produced under strict quality management protocols. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation, to ensure it meets the high standards required for research and process chemistry. Certificates of Analysis (COA) with detailed specifications are provided with every shipment to guarantee traceability and batch-to-batch consistency.

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 light-sensitive nature and propensity for oxidation, prolonged exposure to light and air should be avoided. For long-term storage, consider under an inert atmosphere.
