General description

EMSURE grade solvents are suitable for a broad spectrum of classical lab applications, and are frequently used in regulated and highly demanding lab applications. EMSURE provides worldwide best and most extensive product specifications. We declare our EMSURE range to be in compliance with the ACS, with the reagent part of the European Pharmacopoeia (Reag. Ph Eur) and also with the ISO standards.

Application

n-Heptane is used as a:
  • Solvent in the extraction of sulfur-containing hydrocarbons.
  • Substrate for the double oxidation of medium-chain alkanes.

Other Notes

Discover EMSURE - to be more than sure!
Explore various lab safety accessories and equipment for safe handling of solvents to increase your safety level from the first usage.
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.
