n-Heptane, Environmental Grade, 96+%, Thermo Scientific Chemicals

Description

For Pesticide Residue, Environmental, and GC Analysis

It is used in paints and coatings, as the rubber cement solvent and GC analysis, HPLC, spectrophotometry and environmental testing.used as a primary reference standard in determining the knock rating of carburetor fuels and solvent especially for vegetable oils, low temperature thermo- meters, calibrations, and polymerization reaction medium. The hydroisomerization of n-heptane to form dibranched and tribranched products useful for producing high octane gasoline. water/AOT/n-heptane microemulsions plays an essential role for the synthesis, size control, and passivation of CdS nanoparticles.
