General description

Our biotech solvents offer exceptional quality for reliable RNA extraction, ensuring optimal laboratory performance. With low water content and minimal residue, give clean UV spectra to minimize contamination.
  • High-Quality Biotech Solvents: Designed for optimal laboratory performance with low water content and minimal residues.
  • Ideal for RNA Extraction: Essential for genetic testing and research applications like PCR.
  • Ensures Integrity of Genetic Material: Promotes reliable and reproducible results.
  • Industry Compliant: Suitable for both academic and commercial laboratories, enhancing research efficiency.

Trifluoroacetic acid is a naturally occurring organic solvent and biodegradable by microbial action. It can also be used as a catalyst for various organic transformations, including solvolysis, rearrangements, reductions, oxidations, and trifluoromethylation.

Application

Trifluoroacetic acid can be used as a solvent in the:
  • Mass spectrometry for protein identification.
  • Microwave-irradiated bromination of isoxazoles and pyrazoles with N-bromosuccinimide to synthesize mono-brominated isoxazoles and pyrazoles.
  • Lewis acid-catalyzed 6-endo-digcyclization of 2-(2-arylethynyl)heteroaryl esters to heterocyclic lactones.
  • Electrospinning of cellulose acetate to prepare the corresponding nanofibrous membranes.
