Description

Sodium o-Isobutyl Dithiocarbonate is a specialized organosulfur compound widely utilized as a key intermediate and reagent in organic synthesis and industrial processes. Its primary value lies in its role as a xanthate salt, which is instrumental in the production of flotation agents for mineral processing and as a chain transfer agent in polymer chemistry. This product is essential for manufacturers and R&D facilities in the mining, polymer, and specialty chemical sectors seeking reliable, high-purity raw materials for their formulations.

Application

• Mineral Flotation Reagent: Acts as a powerful collector, particularly for sulfide ores like copper, lead, and zinc, enhancing separation efficiency.
• Polymerization Modifier: Serves as an effective chain transfer agent (CTA) in the production of synthetic rubbers and other polymers to control molecular weight.
• Chemical Synthesis Intermediate: Used in organic synthesis for the introduction of the dithiocarbonate functional group into target molecules.
• Vulcanization Accelerator: Employed in rubber compounding to modify the curing characteristics and properties of the final elastomer.
• Pharmaceutical & Agrochemical Intermediates: Functions as a building block in the synthesis of more complex active ingredients.
• Corrosion Inhibitor Formulation: Incorporated into specialty chemical blends for industrial water treatment and metal protection.

Quality Control

Our products undergo rigorous quality testing to ensure compliance with industry standards and batch-to-batch consistency. Quality is verified through analytical methods including titration, HPLC, and IR spectroscopy. A Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is available for every batch upon request, supporting your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept sealed to prevent absorption of atmospheric moisture, which can compromise product quality and stability.
