Quality Control

Our Disperse Red 258 is manufactured under a stringent quality management system. Every batch undergoes comprehensive analytical testing, including HPLC for purity, spectrophotometry for color strength, and assessments of dispersion stability and particle size distribution. Certificates of Analysis (COA) documenting all key parameters are available upon request to ensure 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 a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent moisture absorption, which can affect product performance.
