Hexafluoroisopropanol (HFIP) is a viscous and colorless liquid with scary odorless. It is an ideal solvent for dissolving polyamides and esters, and it can be used to analyze nylon. Typically, a small amount of sodium trifluoroacetate can be added to the eluent to reduce the aggregation of the sample. HFIP has a certain viscosity, but its boiling point is very low, so we need to analyst under the conditions of 40 ° C to reduce the back pressure of the column. Hexafluoroisopropanol is also a highly polar solvent that results in a non-linearity of the calibration curve obtained from the mixed column bed column. Therefore, Agilent has developed a special column-PL HFIPgel column for this solvent, which has a porous structure that is not affected by solvents.
Hexafluoroisopropanol(1,1,1,3,3,3-Hexafluoro-2-propanol) can be used to prepare a variety of high-end chemicals such as fluorosurfactants, fluorine-containing emulsifiers, fluorine-containing pharmaceuticals, and used as a solvent or cleaning agent for electronics industry.
The drug can be used as a fluorinated solvent to increase the efficiency of the reaction of rhodium (I)-catalyzed [4 + 2] intramolecular addition reaction of ether bound alkynyl diene and the [5 + 2] cycloaddition of alkynyl vinyl cyclopropane. The drug is a liquid peptide chemical solvent, a highly soluble solvent for peptide and peptide intermediates. The drug can be used for the analysis of multiple polymers.

Eyes: Check the victim for contact lenses andremove. Flush victim's eyes with water or normal salinesolution for 20- 30 min, occasionally lifting lower andupper eyelids. Remove contaminated clothing and shoes.Get medical attention immediately. Do not put any oint-ments，oils， or medication in the victim's eyes withoutspecific instructions from a physician. Immediately trans-port the victim after flushing eyes to a hospital even ifno symptoms (such as redness or irritation) develop.Skin: Immediately flood affected skin with water andwash for at least 15 min. Remove and isolate all contami-nated clothing. Gently wash all affected skin areas thor-oughly with soap and water.

If symptoms (such as wheezing, coughing,shortness of breath, or burning in the mouth, throat, orchest) develop, call a physician. In all cases get medicalattention immediately. If the victim is convulsing orunconscious, do not give anything by mouth, ensure that .the victim's airway is open and lay the victim on his/herside with the head lower than the body.
