Quality Control

Every batch of 3-Chloro-2-formylbenzoic Acid is manufactured and tested under a strict quality management system. We provide comprehensive analytical data to ensure the material meets the high standards required for research and industrial synthesis. A detailed Certificate of Analysis (COA) is supplied with each shipment, reporting key parameters such as purity (by HPLC), identity confirmation (by IR and NMR), and levels of specific impurities. Our quality commitment supports applications requiring traceability and consistent performance.

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 nature as a strong acid/organic solvent, keep away from heat, sparks, and incompatible materials such as strong bases and oxidizing agents. The container must be kept tightly sealed to prevent moisture absorption and contamination.
