Quality Control

Our 6-Isoquinolinecarboxylic Acid is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing to ensure high purity and consistency, meeting the stringent requirements of research and development applications. A detailed Certificate of Analysis (COA) documenting identity, purity, and impurity profiles is provided with every shipment.

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 each use to prevent degradation from atmospheric moisture.
