Quality Control

Our 4-(3-Carboxyphenyl)Benzoic Acid is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing to ensure it meets the highest standards of purity and consistency for research and industrial use. A Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with every shipment to guarantee 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.
