Description

Butyl Disulfide is a high-purity organosulfur compound, also known as Di-n-butyl disulfide, valued for its role as a versatile chemical intermediate and additive. Its disulfide linkage makes it a key building block for synthesizing more complex sulfur-containing molecules and for modifying material properties. This product is essential for manufacturers and R&D facilities in the petrochemical, lubricant, polymer, and specialty chemical industries seeking reliable, high-quality raw materials.

Application

• Lubricant and Fuel Additive: Acts as an extreme pressure (EP) agent and anti-wear additive in industrial lubricants and greases.
• Chemical Synthesis Intermediate: Serves as a crucial precursor in the production of other organosulfur compounds, including sulfides, polysulfides, and thiols.
• Polymer Modification: Used as a cross-linking agent or chain transfer agent in the synthesis and modification of rubber and specialty polymers.
• Catalyst and Co-Catalyst Component: Employed in certain catalytic systems within petrochemical refining and organic synthesis processes.
• Corrosion Inhibitor Formulation: A component in formulations designed to protect metal surfaces in industrial applications.
• Flavor and Fragrance Industry: Used in trace amounts as a flavoring agent or aroma chemical, contributing to savory or alliaceous notes.
• Analytical Chemistry: Utilized as a reference standard or reagent in chromatographic analysis and research.

Quality Control

Our Butyl Disulfide is manufactured under strict quality management systems to ensure batch-to-batch consistency and reliability. Each lot undergoes comprehensive analytical testing, including assay by GC or HPLC and impurity profiling, to meet stringent specifications. A Certificate of Analysis (COA) detailing purity, identity, and physical properties is provided with every shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from heat sources and incompatible materials such as strong oxidizing agents. Recommended storage temperature is between 15°C and 25°C. Due to its sensitivity to oxidation, prolonged storage under an inert atmosphere (e.g., nitrogen) is advised for optimal long-term stability.
