Quality Control

Our production of this cationic phthalocyanine dye adheres to stringent quality management systems. Every batch is subjected to comprehensive analytical testing, including spectrophotometric analysis for color strength and purity, to ensure consistency and performance. Certificates of Analysis (COA) documenting key parameters such as shade, solubility, and ionic content are available upon request to support your quality assurance protocols.

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). This material is hygroscopic (moisture-sensitive); ensure the container is kept tightly sealed to prevent absorption of atmospheric moisture, which can affect performance.
