Description

Trisodium 5-(Acetylamino)-4-Hydroxy-3-[[4-Methoxy-3-[[2-(Sulphonatooxy)Ethyl]Sulphonyl]Phenyl]Azo]Naphthalene-2,7-Disulphonate is a high-purity, water-soluble anionic dye intermediate, also known as a reactive dye precursor. This compound is engineered to deliver exceptional color strength and superior reactivity for covalent bonding with textile fibers, ensuring excellent wash and light fastness. It is a critical component for manufacturers in the textile dyeing and specialty chemical industries seeking to produce vibrant, durable shades.

Application

• Primary use in the synthesis of reactive dyes for cotton, viscose, and other cellulosic fibers.
• Key intermediate for producing high-performance azo-based dyes with brilliant red to violet hues.
• Used in the formulation of specialty inks for digital textile printing applications.
• Employed in the coloration of leather and paper where high colorfastness is required.
• Serves as a research chemical for developing new chromophoric systems in academic and industrial R&D.
• Potential use as a biological stain or indicator in analytical chemistry due to its distinct color and structure.

Quality Control

Our production of this dye intermediate adheres to strict quality management systems. Every batch is analyzed using advanced techniques like HPLC and spectrophotometry to ensure consistent purity, color value, and reactive group content. A comprehensive Certificate of Analysis (COA) detailing assay, impurity profile, and physical specifications is provided with each shipment to guarantee it meets your precise formulation requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept sealed in a low-humidity environment to prevent caking and degradation.
