Undecane
Description
Undecane (CAS 1120-21-4), also known as hendecane, is a straight-chain alkane hydrocarbon used as a solvent and carrier fluid across industrial processing applications. It functions as a low-polarity diluent and reference standard in hydrocarbon blending.
The material offers controlled evaporation behavior relevant to formulation and process design. In lubricant and metalworking fluid formulations, it serves as a hydrocarbon carrier for additive packages where a defined solvent is required.
Petroleum and gas laboratories use it as a certified reference component for GC calibration and hydrocarbon fingerprinting in crude oil and condensate analysis. It is essential for precise analytical measurements in these sectors.
In polymer processing, it acts as a process solvent or diluent where a non-polar, mid-chain alkane is specified to control viscosity or carrier behavior. This ensures consistent performance during the manufacturing cycle.
Specialty solvent blends for industrial cleaning and surface preparation also incorporate this alkane to achieve targeted evaporation profiles. It provides a reliable solution for demanding surface treatment requirements.
The product is supplied as a clear, low-viscosity liquid in drum, IBC, and bulk quantities. It is available in high-purity research and analytical grades, typically 98–99%+ purity, for laboratory applications.
Technical-grade material is also available for industrial solvent and blending use cases. Our supply chain ensures that the product meets rigorous industry expectations for consistency and performance in every batch.
