🔹 Basic Information

• Chemical Category: Perylene / Anthraquinone-based dye (Perylene quinone dye)

• Physical Appearance: Blue to deep blue powder

• Solubility: Insoluble in water (as powder); soluble in alkaline solutions and polar organic solvents (e.g., DMF, DMSO)

🔹 Main Uses and Functions

1. High-performance dye / pigment

   • Serves as an intermediate or raw material for reactive dyes or direct dyes used in textiles.

   • Used to color cotton, wool, silk, nylon, and other fibers, producing deep blue to blue-black shades.

   • Features: vivid color, excellent lightfastness, and washfastness, making it a high-fastness dye.

2. Industrial coloring materials

   • Used in inks, coatings, and plastics, especially where heat and light resistance are required.

3. Functional materials (research applications)

   • Can serve as a blue chromophore or photosensitive unit in OLEDs, optical films, and sensors.

🔹 Product Features

• Color tone: Deep blue to blue-black powder

• Lightfastness: Excellent (suitable for long-term outdoor or high-intensity light exposure)

• Heat resistance: Maintains color under high-temperature processing (e.g., polyester or plastic processing)

• Solvent resistance: Stable in organic solvents and oil-based media

• Chemical stability: Aromatic conjugated structure resists oxidation

🔹 Summary

✅ One-sentence summary:

This compound is a high-performance blue perylene dye intermediate, mainly used for coloring textiles, inks, and coatings, with excellent lightfastness, heat resistance, and solvent stability, and is not a controlled chemical.
