Description

Trisodium 1-Amino-4-[(4- Amino-9,10-Dihydro-9,10-Dioxosulphonato-1-Anthryl)Amino]-9,10-Dihydro-9,10-Dioxoanthracenedisulphonate is a high-purity, water-soluble anthraquinone derivative dye intermediate. This compound is valued for its role in synthesizing specialized dyes and pigments with excellent color fastness and stability. It is primarily required by manufacturers in the textile, ink, and specialty chemical industries for producing high-performance colorants.

Application

• Textile Dye Intermediate: A key precursor for synthesizing reactive and acid dyes used in coloring natural and synthetic fibers like cotton, wool, and nylon.
• Inkjet Ink Formulation: Used in the production of high-quality, lightfast pigments for industrial and photographic-grade inkjet inks.
• Specialty Pigment Synthesis: Serves as a building block for creating complex organic pigments used in plastics, coatings, and automotive paints.
• Laboratory Research & Development: Employed as a standard or intermediate in chemical research focused on novel dye structures and photochemical properties.
• Functional Dye Production: Potential use in the synthesis of dyes for non-textile applications, such as in optical data storage or solar cells.

Quality Control

Our production of Trisodium 1-Amino-4-[(4- Amino-9,10-Dihydro-9,10-Dioxosulphonato-1-Anthryl)Amino]-9,10-Dihydro-9,10-Dioxoanthracenedisulphonate adheres to stringent quality management protocols. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation, to ensure consistency and compliance with customer specifications. Certificates of Analysis (COA) documenting all critical parameters are available upon request.

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). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed to prevent absorption of atmospheric moisture, which can affect product quality and handling properties.
