Quality Control

Our 2(1H)-Quinolinone,3-Ethyl-7-Fluoro-4-Hydroxy-(9Ci) is manufactured under a strict quality management system. Every batch undergoes rigorous analytical testing, including HPLC, NMR, and MS, to ensure identity, purity, and consistency. We provide comprehensive Certificates of Analysis (COA) with each shipment, detailing all critical specifications to support your regulatory and R&D documentation needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). Due to its light-sensitive and easily oxidized nature, it is recommended to store the material under an inert atmosphere (e.g., nitrogen or argon) for long-term stability. Keep away from strong oxidizing agents.
