Quality Control

Our Hydroquinone Ditosylate is manufactured under a strict quality management system. Every batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation (IR, NMR), to ensure it meets exacting standards for use in sensitive applications like pharmaceutical synthesis. A detailed Certificate of Analysis (COA) is provided with each shipment, documenting critical 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 area at a controlled room temperature (15-25°C). Keep away from heat, sparks, and open flame. Due to its light-sensitive nature, containers should be kept in opaque packaging or amber glass until use.
