Description

5,6-Dichloro-1-Ethyl-2-Methyl-3-(3-Sulfobutyl)Benzimidazolium Inner Salt is a high-purity, functionalized benzimidazolium derivative with a zwitterionic structure. This compound is valued for its unique combination of a heterocyclic core and a sulfobutyl side chain, which imparts specific solubility and reactivity profiles critical for advanced chemical synthesis. It serves as a key intermediate or functional additive in the development of specialty chemicals, particularly for applications requiring precise molecular architecture and ionic character.

Application

• Pharmaceutical Intermediate: Used in the synthesis of novel active pharmaceutical ingredients (APIs), particularly for drugs targeting specific biological pathways where the benzimidazole scaffold is pharmacologically relevant.
• Liquid Crystal & Electro-Optic Materials: Acts as a precursor or dopant in the production of advanced liquid crystal displays (LCDs) and other electro-optic devices due to its ionic nature and molecular structure.
• Specialty Dyes & Pigments: Serves as a key building block for synthesizing high-performance dyes and organic pigments, where the chlorinated benzimidazole ring enhances lightfastness and color properties.
• Polymer & Resin Modification: Employed as a functional monomer or additive to introduce ionic groups into polymers, improving properties like hydrophilicity, antistatic performance, or adhesion.
• Catalysis & Ligand Synthesis: Utilized in the development of novel catalysts or as a precursor for N-heterocyclic carbene (NHC) ligands in organometallic chemistry and cross-coupling reactions.
• Analytical Chemistry Reagent: Functions as a specialized reagent or standard in chromatographic analysis and other analytical methods for detecting or quantifying related compounds.

Quality Control

Our 5,6-Dichloro-1-Ethyl-2-Methyl-3-(3-Sulfobutyl)Benzimidazolium Inner Salt is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity, NMR and IR for structural confirmation, and tests for residual solvents and moisture content, to ensure it meets exacting standards for research and industrial use. A comprehensive Certificate of Analysis (COA) detailing all specifications is provided with every shipment.

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 nature, the container must be kept tightly sealed after each use to minimize exposure to atmospheric moisture. Keep away from incompatible materials.
