Quality Control

Our 4-Amino-8-Chloro-5-Methoxyquinoline-3-Carboxylic Acid is manufactured under a strict quality management system. Every batch undergoes rigorous analytical testing, including HPLC, NMR, and mass spectrometry, to ensure identity, purity, and consistency. Certificates of Analysis (COA) documenting all specifications are provided with each shipment to guarantee compliance with your research and development requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and 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 to prevent degradation from atmospheric moisture.
