Description

2-Amino-6-(2-(Sulfooxy)Ethylsulfonyl)Naphthalene-1-Sulfonic Acid is a high-purity, functionalized naphthalene derivative designed for advanced chemical synthesis. This compound matters as a key reactive intermediate, offering a unique combination of amino, sulfonic acid, and activated sulfonyl ester groups for creating complex, water-soluble molecules. It is primarily needed by manufacturers in the dye and pigment industry for producing high-performance, fiber-reactive dyes, as well as by researchers developing specialized polymers and biochemical conjugates.

Application

• Reactive Dye Intermediate: A critical building block for synthesizing high-quality, fiber-reactive dyes for textiles, particularly for cotton and cellulose fibers.
• Pigment Manufacturing: Used in the production of specialized organic pigments requiring enhanced solubility and chromophoric properties.
• Bioconjugation Linker: Serves as a bifunctional linker in biochemical research for attaching molecules to proteins or other biomolecules via its amine-reactive sulfonyl ester group.
• Polymer Modification: Employed to introduce sulfonic acid groups into polymer backbones, improving hydrophilicity and ion-exchange capacity.
• Chemical Synthesis: Acts as a versatile intermediate in organic synthesis for pharmaceuticals and agrochemicals due to its multiple functional sites.
• Analytical Reagent: Can be used in the development of chromogenic and fluorescent probes or sensors.

Quality Control

Our 2-Amino-6-(2-(Sulfooxy)Ethylsulfonyl)Naphthalene-1-Sulfonic Acid is manufactured under a strict quality management system. Every batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation, to ensure it meets precise specifications for use in sensitive applications like dye synthesis. A comprehensive Certificate of Analysis (COA) detailing purity, impurity profile, and physical characteristics is provided with each shipment to guarantee traceability and consistency.

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 sealed to prevent absorption of atmospheric moisture, which can affect product stability and performance.
