Quality Control

Our 6-Chloro-1-Methyl-4-Oxo-1,4-Dihydroquinoline-3-Carboxylic Acid is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing, including HPLC, NMR, and IR spectroscopy, to ensure high purity and consistency. Certificates of Analysis (COA) detailing all specifications are provided with every shipment to guarantee compliance with your research and production 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). This material is hygroscopic (moisture-sensitive) and light-sensitive; therefore, containers must be kept sealed and away from direct light sources to maintain stability and purity.
