Quality Control

Our Phenylhydroquinone is manufactured under a strict quality management system. Every batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation, to ensure it meets exacting standards. A Certificate of Analysis (COA) detailing all test results is provided with each shipment. We support compliance with global regulatory frameworks, and specifications can be aligned with customer-specific requirements for pharmaceutical or advanced material 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 property of being easily oxidized, it is recommended to store under an inert atmosphere (e.g., nitrogen) for long-term storage. Keep away from strong oxidizing agents, strong acids, and strong bases.
