Overview
Dodecane (CAS 112-40-3 ), also known as duodecane, is a straight-chain alkane hydrocarbon used as a non-polar solvent and carrier across industrial and specialty chemical applications.
Its low reactivity and controlled evaporation profile make it a preferred diluent in formulations where solvent residue and compatibility with sensitive substrates are procurement considerations.
In coatings and adhesives, dodecane functions as a slow-evaporating solvent that aids film formation and controls viscosity in solvent-borne systems for industrial use.
Lubricant formulators use it as a base fluid component or diluent in metalworking fluids, where its hydrocarbon structure provides stable lubrication under moderate operating conditions.
Personal care manufacturers incorporate it as a lightweight carrier in emollient formulations, fragrance delivery systems, and skin-feel modifiers in leave-on products.
It also serves as a reference solvent and calibration standard in analytical and laboratory environments where a well-characterized hydrocarbon matrix is required for testing.
Dodecane is supplied as a clear, low-viscosity liquid in drum, IBC, and bulk quantities. Standard commercial grades include technical-grade and high-purity research-grade specifications.
Purity levels typically range from 99%+ for laboratory applications. Buyers should confirm hydrocarbon distribution and impurity profiles when sourcing for sensitive formulation or analytical use.
