Description

Butylisobutylsulfide CAS NO 1741-85-1 is a specialized organosulfur compound characterized by its unique sulfide linkage between butyl and isobutyl groups. This structure makes it a valuable intermediate and functional additive in various high-performance chemical syntheses. It is primarily sought after by manufacturers in the polymer, lubricant, and specialty chemical industries for its role in modifying material properties and facilitating specific organic reactions.

Application

• Polymer Additive: Acts as a chain transfer agent or modifier in the production of synthetic rubbers and specialty polymers to control molecular weight and properties.
• Lubricant and Fuel Additive: Serves as an extreme pressure (EP) additive and anti-wear agent in industrial lubricants and greases.
• Chemical Synthesis Intermediate: A key building block for synthesizing more complex sulfur-containing compounds, such as certain pharmaceuticals and agrochemicals.
• Flavor and Fragrance Industry: Used in the controlled synthesis of sulfur-based aroma chemicals, contributing to savory or alliaceous notes.
• Corrosion Inhibitor Precursor: Employed in formulations for metalworking fluids and coatings to provide protective sulfide layers.
• Catalyst and Ligand Component: Finds application in organometallic chemistry and catalysis due to its electron-donating sulfide group.

Quality Control

Our Butylisobutylsulfide is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity. Quality is verified through a comprehensive suite of analytical techniques including Gas Chromatography (GC) and Infrared Spectroscopy (IR). A Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with every shipment to guarantee it meets your specific application requirements.

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). Keep away from strong oxidizing agents, strong acids, and heat sources. Due to its organic sulfide nature, it is recommended to store under an inert atmosphere for long-term stability to prevent oxidation.
