Description

o-Ethyl S-(3-Sulphopropyl) Dithiocarbonate, Sodium Salt is a specialized organosulfur compound with significant utility as a versatile intermediate and functional additive. Its core value lies in its ability to act as a chain transfer agent, polymerization modifier, and surface-active component, enabling precise control in synthetic processes. This chemical is essential for R&D chemists and production engineers in the polymer, specialty chemical, and pharmaceutical intermediate sectors seeking to fine-tune molecular weight and introduce specific functional groups.

Application

• Polymer Synthesis: Primarily used as a chain transfer agent (CTA) or reversible addition-fragmentation chain-transfer (RAFT) agent in the controlled radical polymerization of acrylics, styrenics, and other vinyl monomers.
• Specialty Chemical Intermediate: Serves as a key building block for synthesizing surfactants, lubricant additives, and corrosion inhibitors due to its sulphopropyl and dithiocarbonate functionalities.
• Pharmaceutical Manufacturing: Employed in the research and development of active pharmaceutical ingredients (APIs) and prodrugs that require a tailored release mechanism or specific sulfur-based chemistry.
• Surface Modification Agent: Used to functionalize surfaces of nanoparticles, polymers, or other materials to alter wettability, adhesion, or biocompatibility properties.
• Crosslinking and Curing Agent: Acts as a co-agent in rubber vulcanization or as a crosslinker for specific polymer systems, enhancing thermal and mechanical stability.
• Analytical Chemistry: Can be utilized as a derivatization agent or a standard in chromatographic analysis for sulfur-containing compounds.

Quality Control

Every batch of o-Ethyl S-(3-Sulphopropyl) Dithiocarbonate, Sodium Salt is manufactured under a strict quality management system. We perform comprehensive in-process and final release testing, including identity confirmation, purity assay, and impurity profiling, to ensure consistent performance and reliability for your critical applications. A detailed Certificate of Analysis (COA) documenting all test results is provided with each shipment.

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 absorption of atmospheric moisture. For long-term storage, consider using an inert atmosphere to minimize potential oxidation.
