Application

HX0078P-1 is packaged in poly coated glass bottles
Heptane can be used as a solvent in the:
  • Synthesis of advanced nanomaterials.
  • Polymerization of certain monomers, promoting the formation of high molecular weight polymers.
  • Formulation of paints, coatings, and adhesives due to its effective solvent properties.

General description

Heptane, a linear alkane, is characterized by its low viscosity and high volatility, making it an essential solvent in various industrial and laboratory applications. It is commonly utilized in the extraction and purification of organic compounds, as well as in chromatography, due to its ability to dissolve a wide range of non-polar substances.
We are committed to bringing you Greener Alternative Products, which adhere to one or more of The 12 Principles of Greener Chemistry. Heptane is an environmentally preferable solvent compared to hexane and thus align with "Safer Solvents and Auxiliaries". Click here for more information.
