It is a reference fuel with the cetane number 100 and is employed in determining the cetane number of diesel fuels. The mechanism of the oxidation of hexadecane in the gas-phase has been described. The density, speed of sound, adiabatic compressibility and compressed liquid density of hexadecane have been determined. The performance of platinum/zeolite catalysts for the hydroisomerization of n-hexadecane has been assessed. The thermal degradation of n-hexadecane forms n-alkanes and 1-alkenes as key products.ApplicationHexadecane has been used as a phase change material (PCM) in the preparation of hexadecane/xGnP (exfoliated graphite nanoplatelet), a composite PCM loaded with xGnP.Packaging100, 500, 6×500 mL in glass bottle

Hexane (mixture of isomers) can be isolated from petroleum by distillation or by cracking. They form major constituents of petroleum ether. It is a non-renewable organic solvent mainly used for the dissolution and extraction of oils and fats. Separation of the isomeric forms of hexane on the basis of degree of branching using Fe2(BDP)3 (BDP2- = 1,4-benzenedipyrazolate) has been reported.ApplicationHexane (n-hexane) has been used in the preparation of precursor required for the synthesis of chiral stationary phase (IMPCSP). IMPCSP was employed for the enantioseparation of racemic drugs by high-performance liquid chromatography (HPLC) and supercritical fluid chromatography (SFC).

It is an ideal candidate as a hydrogen source in fuel cell technology due to its high H/C ratio, low propensity for soot generation, relatively low reforming temperature and as it exists in liquid state at room temperature. In a direct methanol fuel cell (DMFC), methanol undergoes oxidation with air to generate electricity. The olefins (ethylene or propylene) formed from methanol via MTO (methanol-to-olefins) process, can be an alternate to oil and gas to produce hydrocarbon fuels.
Thermochemical conversion of methanol to C2-C10 hydrocarbons in the presence of shape-selective zeolites has been reported. Its oxidation on Ru-Pt catalyst system by ruthenium ad-atoms has been proposed.ApplicationMethanol can be used as a mobile phase in reversed-phase liquid chromatography.
Methanol (MeOH) has been used in the wholemount immunofluorescence studies of embryonic tissues.
It may be used in the following studies:- Colony forming unit-fibroblast assay of bone marrow mononuclear cells.
- As solvent for the preparation of extracts of hyphae of Aspergillus for the estimation of gliotoxin by reversed phase-HPLC.
- Immunofluorescence studies.
- To compose the eluent for the ion-pair reverse-phase HPLC isolation of nucleotides and their decomposition products.
