Dodecane ≥99% is a straight-chain alkane solvent widely used in laboratory applications, fuel testing, and as a reference standard for chromatography. Industrially, it also serves as a medium for organic synthesis, a distillation chaser, a metal degreasing solvent, and a processing aid in paper and rubber manufacturing. It serves as a nonpolar solvent for extracting oils, resins, and other hydrophobic compounds, and is also employed in calibration and analytical procedures. This chemical has a CAS number of 112-40-3, with the molecular formula CH3(CH2)10CH3 and a molecular weight of 170.33 g/mol. It is stored at ambient conditions but carries a Danger signal word due to its flammability and aspiration hazard. Molekula supplies Dodecane ≥99% from research to bulk quantities with full documentation and ISO 9001:2015 traceability.

Frequently asked questions
What is dodecane (CAS 112-40-3) commonly used for?
Dodecane is primarily used as a solvent, fuel additive, and reference standard in chromatography, as well as in formulations for coatings, inks, and cleaning agents.
What is the molecular formula and molecular weight of dodecane?
The molecular formula is CH₃(CH₂)₁₀CH₃, and the molecular weight is 170.33 g/mol.
What safety classification does dodecane have, and how should it be stored?
Dodecane carries the signal word 'Danger' because of its aspiration hazard (H304: may be fatal if swallowed and enters airways). It is also a combustible liquid (H227), and repeated exposure may cause skin dryness or cracking (EUH066). Store in a tightly sealed container at ambient temperature, away from ignition sources.
Does Molekula offer dodecane in different grades (e.g., analytical, technical)?
Molekula supplies dodecane at ≥99% purity, suitable for most industrial and analytical applications. Higher-purity grades may be available upon request.
Can Molekula supply dodecane in bulk quantities?
Yes, we offer dodecane in bulk, with packaging options including drums (typically 200L) and IBCs (1000L), depending on order volume.
What documentation is provided with a dodecane order?
Each order includes a Certificate of Analysis (CoA), Material Safety Data Sheet (MSDS), and a packing slip with batch details and storage instructions.
