Quality Control

Every batch of 4-(4-Isopropoxy-Phenoxy)-Benzoic Acid is manufactured under a strict quality management system and undergoes comprehensive analytical testing to ensure identity, purity, and consistency. Our standard grade meets a typical purity specification of ≥97.0% (HPLC), with higher purity grades available upon request. A detailed Certificate of Analysis (COA) is provided with each shipment, documenting key parameters such as assay, related substances, and residual solvents.

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 after opening to prevent moisture absorption, which may affect stability and handling properties. Keep away from heat sources and incompatible materials.
