Quality Control

Every batch of Isoxazolo[5,4-B]Pyridin-6(7H)-One, 4-Hydroxy-3-Methyl- (9Ci) is manufactured and tested under a strict quality management system. Our products undergo rigorous quality testing to ensure compliance with industry standards for research and development use. Certificates of Analysis (COA) detailing purity, identity, and impurity profiles are available upon request to support your regulatory and quality assurance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place 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.
