Description

2-(2-(2-Oxo-2-((3,6,8-Trisulfonaphthalen-1-Yl)Amino)Ethoxy)Ethoxy)Aceticacid is a specialized, high-purity organic intermediate featuring a naphthalene trisulfonate core linked to a polyether acetic acid chain. This compound matters for its unique combination of strong water solubility, conferred by the sulfonate groups, and a reactive terminal carboxylic acid, enabling precise conjugation and derivatization. It is primarily needed by manufacturers in the dye and pigment, pharmaceutical intermediate, and advanced material research sectors for creating functionalized molecules with enhanced solubility and specific binding properties.

Application

• Fluorescent Dye & Probe Synthesis: Acts as a key hydrophilic linker and solubilizing component in the production of advanced fluorescent tags and molecular probes for bioimaging and diagnostics.
• Pharmaceutical Intermediate: Used in the research and development of drug candidates, particularly where enhanced aqueous solubility is required for active pharmaceutical ingredients (APIs).
• Functional Polymer & Material Science: Serves as a monomer or modifier for creating water-soluble polymers, hydrogels, and specialty coatings with tailored ionic and chemical properties.
• Chromatography & Analytical Reagents: Employed in the synthesis of specialized ligands or stationary phases for separation techniques like ion-exchange chromatography.
• Chemical Sensor Development: Utilized as a building block for constructing chemosensors due to its naphthalene fluorophore and multiple sites for functional group attachment.
• Catalyst & Ligand Design: Functions as a precursor for water-soluble ligands used in homogeneous catalysis in aqueous media.

Quality Control

Every batch of 2-(2-(2-Oxo-2-((3,6,8-Trisulfonaphthalen-1-Yl)Amino)Ethoxy)Ethoxy)Aceticacid is manufactured under a strict quality management system. Our products undergo rigorous analytical testing, including HPLC, NMR, and mass spectrometry, to ensure identity, purity, and consistency. Certificates of Analysis (COA) detailing batch-specific results are provided and can be tailored to meet specific customer or regulatory requirements.

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 under anhydrous conditions to prevent degradation. Keep away from incompatible materials such as strong acids and strong oxidizing agents.
