Application

Ethanol is used as a solvent:
  • to Prepare stock standard and working solutions of fenpropathrin and bifenthrin.
  • in alternative and sustainable solvents for green analytical chemistry.

General description

We are committed to bringing you Greener Alternative Products, which adhere to one or more of The 12 Principles of Greener Chemistry. Ethanol is environmentally preferable green solvent and thus it aligns with "Safer Solvents and Auxiliaries". and "Use of Renewable feedstocks". Click here for more information.

With their high degree of UV transmittance, low particle count, low acidity and alkalinity, and low evaporation residue level, LiChrosolv solvents are ideal for reproducible separations. Since separations are carried out under gradient conditions in analytical HPLC, we offer solvents in "gradient” and "isocratic" grades. This can minimize the gradient effect of the solvent involved.
