Description

Dihydrogen 3-[[4-[(4-chloro-6-methoxy-1,3,5-triazin-2-yl)amino]-2-sulphonatophenyl]amino]-7-[ethyl[(3-sulphonatophenyl)methyl]amino]-5-(4-sulphonatophenyl)phenazinium, disodium salt is a high-purity, water-soluble reactive dye intermediate of significant commercial importance. Its complex molecular structure, featuring multiple sulphonate groups and a reactive triazine moiety, makes it a critical precursor for synthesizing high-performance dyes and pigments. This compound is essential for manufacturers in the textile, ink, and specialty chemical industries seeking to produce vibrant, colorfast, and wash-fast coloring agents.

Application

• Reactive Dye Synthesis: Primary intermediate for manufacturing high-quality fiber-reactive dyes used in cotton, wool, and nylon dyeing.
• Textile Industry: Production of dyes offering excellent wash-fastness, light-fastness, and brilliant shades for the global textile market.
• Inkjet Inks: Key component in the formulation of advanced pigment and dye-based inks for industrial and commercial printing.
• Specialty Pigments: Used in the synthesis of complex organic pigments for plastics, coatings, and high-performance applications.
• Research & Development: Serves as a sophisticated building block in chemical R&D for novel chromophores and functional materials.
• Biological Staining: Potential use as a precursor for developing specialized stains in histology and microscopy due to its phenazinium core.

Quality Control

Our production of dihydrogen 3-[[4-[(4-chloro-6-methoxy-1,3,5-triazin-2-yl)amino]-2-sulphonatophenyl]amino]-7-[ethyl[(3-sulphonatophenyl)methyl]amino]-5-(4-sulphonatophenyl)phenazinium, disodium salt adheres to stringent quality management protocols. Every batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation, to ensure consistency and compliance with customer specifications. Certificates of Analysis (COA) detailing batch-specific results are provided and can be tailored to meet the requirements of ISO, GMP, or other relevant quality systems for industrial chemical intermediates.

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 absorption of atmospheric moisture, which can affect product stability and performance. Keep away from incompatible materials.
