Quality Control

Our 2,5-Di-sec-Dodecylhydroquinone is manufactured under a strict quality management system. Every batch undergoes rigorous analytical testing to ensure it meets high-purity specifications and consistent performance. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with each shipment to guarantee traceability and compliance with your technical requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This product is easily oxidized; for long-term storage, maintaining an inert atmosphere (e.g., under nitrogen) in the container headspace is recommended to preserve quality.
