Quality Control

Our 2-(4-Hydroxyphenoxy)Phenol is manufactured under a strict quality management system. Every batch undergoes comprehensive analytical testing to ensure it meets the required specifications for identity, purity, and impurity profiles. We provide a detailed Certificate of Analysis (COA) with each shipment, documenting key parameters such as assay, related substances, and residual solvents. For customers with specific regulatory needs, we can support documentation for compliance with standards such as REACH, FDA DMF (where applicable), and ICH guidelines.

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 sensitivity to oxidation, it is recommended to store the product under an inert atmosphere (e.g., nitrogen) for long-term preservation. Keep away from strong oxidizing agents, strong acids, and strong bases.
