Description

N,n-Bis(4-Sulfobutyl)-3,5-Dimethylaniline Disodium Salt is a high-purity, water-soluble aniline derivative primarily used as a key intermediate in the synthesis of specialized dyes and functional materials. Its value lies in its dual sulfonate groups, which impart excellent solubility and reactivity, making it a critical building block for creating colorants with specific performance characteristics. This compound is essential for manufacturers in the dye and pigment, specialty chemical, and advanced material research sectors seeking to develop novel products.

Application

• Reactive Dye Intermediate: A crucial precursor for synthesizing reactive dyes used in textile coloring, particularly for cotton and other cellulose fibers.
• Functional Dye Synthesis: Used in the production of specialized dyes for ink-jet printing, LCD color filters, and photographic applications.
• Biomolecular Staining Agent Precursor: Serves as an intermediate in the manufacture of staining agents and fluorescent probes for biological and diagnostic applications.
• Polymer Modification: Employed to introduce sulfonate and aniline functionalities into polymers to alter solubility, conductivity, or dye-affinity properties.
• Research & Development: A valuable building block in organic synthesis and material science research for creating new chromophores and functional molecules.
• Electrochemical Sensor Development: Potential use in the synthesis of components for chemical sensors due to its electroactive aniline core.

Quality Control

Our N,n-Bis(4-Sulfobutyl)-3,5-Dimethylaniline Disodium Salt is manufactured under a strict quality management system. Every batch undergoes rigorous analytical testing to ensure consistent purity and performance. A comprehensive Certificate of Analysis (COA) detailing identity, assay, and impurity profiles is provided with each shipment to guarantee it meets your specific application 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 tightly sealed after opening to prevent absorption of atmospheric moisture, which can affect product quality.
