Quality Control

Our 1-(2-Hydroxy-3-Sulfopropyl)-Pyridinium Betane is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing to ensure consistent purity, identity, and performance. Certificates of Analysis (COA) detailing key parameters such as assay, moisture content, and heavy metals are provided to guarantee compliance with your specific application 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). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept sealed to prevent absorption of atmospheric moisture, which can affect product quality and handling properties.
