Quality Control

Our Chloramine Rubine is produced under a stringent quality management system. Each batch undergoes comprehensive analytical testing to ensure it meets precise specifications for color strength, hue, and chemical purity. Certificates of Analysis (COA) documenting key parameters such as assay, impurity profile, and physical properties are available for every shipment to guarantee traceability and compliance with your formulation requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at ambient temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept sealed when not in use to prevent moisture absorption, which can affect product performance.
