Uses:
3,4,9,10-Perylenetetracarboxylic dianhydride (commonly abbreviated as PTCDA, CAS No.: 128-69-8) is a highly conjugated organic compound that typically appears as a dark red or orange-red powder. In the context of the Dyes Grade, it serves as a fundamental and high-performance precursor for synthesizing perylene-based dyes and pigments.
Primary Uses (Dyes Grade)
High-Performance Pigment Synthesis: It is a critical intermediate for manufacturing premium organic pigments, such as Pigment Red 224, Perylene Red Y, and Irgazin Red BPT.
Specialty Dyes Production: It is used to synthesize vat dyes, notably Vat Red K and Vat Red R, which are essential in textile dyeing and printing.
Advanced Coatings & Plastics: The resulting perylene pigments are widely dispersed into drying oils, paints, lacquers, natural resins, rubber, and synthetic plastics (such as PVC, polystyrene, and polyethylene) to provide vibrant, durable coloration.
Selling Points
Exceptional Color Performance: Dyes and pigments derived from PTCDA are renowned for their brilliant color, high tinting strength, and excellent opacity, making them ideal for high-end coloring applications.
Superior Durability & Stability: Perylene pigments offer outstanding resistance to heat, light (UV stability), and weathering, ensuring long-lasting color retention in harsh outdoor or industrial environments.
Versatile Compatibility: It exhibits excellent dispersion properties and chemical compatibility across a wide range of high-molecular-weight organic materials and complex coating formulations.
High Purity Availability: Industrial-grade PTCDA is readily available with high purity specifications (e.g., ≥98% to 99%), ensuring consistent and reliable synthesis of premium dye intermediates.
Safety Considerations
While not classified as highly toxic, PTCDA can cause skin and serious eye irritation. Appropriate personal protective equipment (gloves and eye protection) should be worn during handling, and it should be stored in a cool, dry, and dark place.
