Quality Control

Our Hydroquinone Monosulfate Potassium Salt is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing to ensure identity, purity, and consistency. We provide Certificates of Analysis (COA) with key parameters including assay, impurity profile, and loss on drying. Specifications can be aligned with customer requirements for technical or high-purity grades.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic and easily oxidized nature, the container must be kept tightly sealed under an inert atmosphere after opening to minimize moisture uptake and oxidative degradation. Keep away from incompatible materials.
