Quality Control

Our production of C.I. Reactive Blue 163 adheres to stringent quality management protocols to ensure batch-to-batch consistency and performance reliability. Every lot is tested against key parameters including color strength, shade, solubility, and fixation properties. Certificates of Analysis (COA) detailing these specifications are available upon request to support your quality assurance processes.

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 tightly sealed after each use to prevent moisture absorption, which can affect product performance.
