General description

2,2,2-Trifluoroethanol (TFE) is a fluorinated compound used as a solvent in organic synthesis. Peptides and proteins are experimentally studied using TEE as a cosolvent. In TFE, hydrogen peroxide is effective for oxidizing sulfur compounds.

Application

2,2,2-Trifluoroethanol is used as a solvent:
  • In the preparation of nylon/Ag composite nanofibers by electrospinning method.
  • To study the combination of two polymers PANI (polyaniline) and PHB (polyhydroxy-butyrate).

Features and Benefits

2,2,2-Trifluoroethanol is more acidic than ethanol due to the presence of electronegative trifluoromethyl group.

Protocols

Fmoc resin cleavage and deprotection follows the difficult task of detaching the peptide from the resin support and removing all the side-chain protecting groups of the amino acid residues to yield the desired peptide.

Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
