Quality Control

Our 5-Chloromaleylacetic Acid is produced under stringent quality management systems. Every batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation via spectroscopic methods, to ensure it meets exacting standards for research and industrial use. A detailed Certificate of Analysis (COA) is provided with each shipment, documenting key parameters such as assay, impurity profile, and physical characteristics.

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 nature as a strong acid/organic solvent, keep away from heat, sparks, open flames, and incompatible materials such as strong bases and oxidizing agents. Ensure containers are kept tightly sealed when not in use to maintain product integrity.
