Description

(2-Carboxyethyl)Dimethylsulfonium Chloride is a versatile organosulfur compound featuring a reactive sulfonium center and a carboxylic acid functional group. This unique bifunctional structure makes it a valuable intermediate for synthesizing specialty chemicals and modifying biomolecules. It is particularly sought after by research institutions and manufacturers in the pharmaceutical, agrochemical, and materials science sectors for applications ranging from peptide synthesis to the development of functional polymers.

Application

• Pharmaceutical Intermediate: Used in the synthesis of active pharmaceutical ingredients (APIs) and prodrugs, particularly where sulfonium-based leaving groups or specific molecular modifications are required.
• Bioconjugation Reagent: Acts as a key reagent for modifying peptides, proteins, and other biomolecules, enabling the introduction of carboxylate groups or serving as a precursor for other functional handles.
• Polymer Chemistry: Employed as a monomer or cross-linking agent in the production of specialty polymers, including polyelectrolytes and materials with specific ionic or responsive properties.
• Agrochemical Synthesis: Serves as a building block for creating novel herbicides, fungicides, and plant growth regulators that leverage its reactive sulfonium moiety.
• Chemical Research: Utilized in organic synthesis as a methylthiolation agent or a precursor for generating dimethyl sulfide and other sulfur-containing compounds under controlled conditions.
• Surface Modification: Applied in material science to functionalize surfaces, creating coatings with specific chemical or physical characteristics.

Quality Control

Our (2-Carboxyethyl)Dimethylsulfonium Chloride is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation by NMR and IR spectroscopy, to ensure it meets the high standards required for research and industrial synthesis. A detailed Certificate of Analysis (COA) is provided with every shipment, documenting key parameters such as assay, impurity profile, and moisture content.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after each use to prevent degradation from atmospheric moisture. Keep away from incompatible materials such as strong bases and strong oxidizing agents.
