Quality Control

Our 2-Chloro-4-(4-Cyanophenyl)Benzoic Acid is manufactured under strict quality management systems. Every batch undergoes comprehensive analytical testing, including HPLC for purity, NMR and IR for structural confirmation, and residual solvent analysis, to ensure it meets the high standards required for advanced synthesis. A detailed Certificate of Analysis (COA) is provided with each shipment, guaranteeing traceability and compliance with your specifications.

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 nature, the container must be kept tightly sealed to prevent moisture absorption, which can affect product stability and performance.
