Quality Control

Our 4-Isoquinolinamine, 2-Oxide (9Ci) is manufactured under strict quality control protocols to ensure batch-to-batch consistency and high purity. We provide comprehensive Certificates of Analysis (COA) for each lot, detailing purity, identity, and impurity profiles. Our quality system is designed to meet the stringent requirements of research and development applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area. Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed under dry, inert conditions to prevent degradation. Recommended long-term storage temperature is 2-8°C.
