Quality Control

Our Phenylsulfate is produced under a strict quality management system. Each batch undergoes comprehensive analytical testing to ensure identity, purity, and consistency. We provide detailed Certificates of Analysis (COA) with key parameters including assay, impurity profile, and physical characteristics. Our quality commitment ensures the material meets the stringent requirements for use as a pharmaceutical intermediate and in other critical applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area. Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent degradation from atmospheric moisture. Recommended storage temperature is 2-8°C for long-term stability.
