2-methylundecane

2-Methylundecane (CAS 7045-71-8) is a branched-chain alkane used as a solvent carrier and lubricant base component.

Where is 2-methylundecane used?

• Lubricant and metalworking fluids: base fluid component or diluent, contributing to film formation and reduced friction in cutting and machining operations
• Automotive: carrier solvent in fuel additives and specialty lubricant blends where controlled evaporation and compatibility with hydrocarbon systems are required
• Printing and packaging: incorporated into ink formulations and release coatings where solvent balance and substrate compatibility are critical to print quality
• Personal care: lightweight emollient carrier in anhydrous and oil-phase formulations, improving spreadability without heavy residue
• Its branched structure supports controlled viscosity profiles and low-temperature performance.

Good to know: Purity levels are typically at 98% or higher depending on the specific supplier and manufacturing process. Bulk availability may vary by region, and buyers should confirm specification sheets for trace impurity profiles.

Commercial specifications

• Purity levels typically at 98% or higher
• Clear liquid in drum and IBC quantities
• Technical grade is the primary commercial specification
