Quality Control

Our 4-(2-Carboxyphenyl)Benzoic Acid is manufactured under a strict quality management system. Each batch is subjected to comprehensive analytical testing, including HPLC for purity and identity confirmation, to ensure it meets the stringent requirements of our global B2B clients. A detailed Certificate of Analysis (COA) is provided with every shipment, guaranteeing traceability and consistent quality for your critical applications.

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 (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent degradation from atmospheric moisture.
