What is Dodecane?
Dodecane (CAS 112-40-3), also known as duodecane, is a straight-chain alkane hydrocarbon used as a non-polar solvent and carrier.
Where is Dodecane used?
- Coatings and adhesives: slow-evaporating solvent aiding film formation and viscosity control in solvent-borne systems
- Lubricants: base fluid component or diluent in metalworking fluids
- Personal care: lightweight carrier in emollient formulations, fragrance delivery and skin-feel modifiers
- Analytical laboratories: reference solvent and calibration standard
- It serves as a diluent where solvent residue and substrate compatibility are procurement considerations.
Good to know: Buyers should confirm hydrocarbon distribution and impurity profiles when sourcing for sensitive formulation or analytical use.
Commercial specifications
- Purity typically 99%+ for laboratory applications
- Technical-grade and high-purity research-grade specifications
- Clear, low-viscosity liquid in drum, IBC and bulk quantities
