Quality Control

Our 4-Phenoxybenzoic Acid is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing to ensure it meets the required specifications for identity, purity, and impurity profiles. We provide detailed Certificates of Analysis (COA) with every shipment, documenting key parameters such as assay, related substances, and residual solvents. Our quality commitment ensures batch-to-batch consistency and reliability for your critical applications.

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 hygroscopic nature, the container must be kept tightly sealed to prevent moisture absorption, which can affect product stability and performance. Keep away from incompatible materials such as strong oxidizing agents, strong bases, and strong acids.
