Description

1-Dimethylcarbamoyl-4-(2-Sulfoethyl)Pyridinium Betaine is a specialized zwitterionic compound, also known as a sulfobetaine, featuring a pyridinium core functionalized with a dimethylcarbamoyl group and a sulfonate moiety. This unique structure makes it a valuable intermediate and functional additive, particularly prized for its ability to impart solubility, stability, and specific surface-active properties in demanding formulations. It is primarily utilized by researchers and manufacturers in the pharmaceutical, agrochemical, and specialty chemical industries for applications ranging from synthesis to advanced material science.

Application

• Pharmaceutical Intermediate: Serves as a key building block in the synthesis of active pharmaceutical ingredients (APIs), particularly those requiring zwitterionic character for enhanced bioavailability or specific receptor interactions.
• Agrochemical Synthesis: Used in the production of advanced herbicides, fungicides, or plant growth regulators where its polar, charged structure can influence activity and environmental fate.
• Specialty Surfactant/Additive: Functions as a high-performance surfactant or viscosity modifier in formulations requiring compatibility with both aqueous and organic phases, such as in coatings, inks, or personal care products.
• Bioconjugation & Protein Chemistry: Acts as a linker or modifying agent for biomolecules, leveraging its reactive groups to attach labels, drugs, or polymers while maintaining solubility.
• Polymer & Material Science: Incorporated into polymers to create materials with permanent dipole moments, anti-fouling properties, or enhanced hydrophilicity for membranes and hydrogels.
• Catalysis & Ligand Design: Employed as a precursor for designing novel ligands in transition metal catalysis, where the betaine structure can influence catalyst solubility and activity.
• Analytical Chemistry Reagent: Utilized as a standard, derivatization agent, or mobile phase additive in chromatographic separations, particularly for polar compounds.
• Electrolyte Component: Investigated for use in specialized electrochemical applications, such as in certain battery electrolytes or electroplating baths, due to its ionic nature.

Quality Control

Every batch of 1-Dimethylcarbamoyl-4-(2-Sulfoethyl)Pyridinium Betaine is produced and tested under a strict quality management system to ensure consistency and reliability for industrial and research use. Our standard quality control includes comprehensive analysis to confirm identity, purity, and the absence of critical impurities. Certificates of Analysis (COA) detailing lot-specific results are provided with each shipment and are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (typically 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 handling properties.
