1,1,1,3,3,3-Hexafluoro-2-propanol Usage And Synthesis
  • DescriptionHexafluoroisopropanol (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.
  • Clinical applicationHexafluoroisopropanol(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.
  • Hazards

    1,1,1,3,3,3-Hexafluoro-2-propanol derives from a propan-2-ol. It is a clear colorless oily liquid with an aromatic odor. (NTP, 1992) Combustible, may cause burns to skin, eyes and mucous membranes.

  • Preparation

    1,1,1,3,3,3-Hexafluoro-2-propanol is prepared from hexafluoropropylene through hexafluoroacetone, which is then hydrogenated.
    (CF3)2CO + H2 → (CF3)2CHOH

  • Chemical Properties1,1,1,3,3,3-Hexafluoro-2-propanol (HFIP) is a clear, colorless, oily, combustible liquid. Odor is described as aromatic.
  • Chemical PropertiesColorless liquid
  • UsesHexafluoroisopropanol is used to produce high-end chemicals, such as fluorinated surfactants, fluorinated emulsifier and fluorinated medicine, etc. HFIP is used as a solvent or cleaner in electronic industry.
  • Uses1,1,1,3,3,3-Hexafluoro-2-propanol effects the native state of proteins, denaturing them as well as stabilizing the α-helical conformation of unfolded proteins and polypeptides.
  • Uses

    It is used as a polar solvent and exhibits strong hydrogen bonding properties.It dissolves substances that are hydrogen-bond acceptors, such as amides, ethers and a wide range of polymers, including those that are not soluble in the most common organic solvents.

  • UsesUsually used for preparing hexafluoroalcohol-functionalized methacrylate polymers for lithographic/nanopatterning materials.
  • DefinitionChEBI: An organofluorine compound formed by substitution of all the methyl protons in propan-2-ol by fluorine. It is a metabolite of inhalation anesthetic sevoflurane.
  • Air & Water ReactionsWater soluble.
  • Reactivity Profile1,1,1,3,3,3-Hexafluoro-2-propanol is incompatible with acids, acid chlorides and oxidizing agents.
  • Fire Hazard1,1,1,3,3,3-Hexafluoro-2-propanol is probably combustible.
  • Potential ExposureA specialty solvent for some poly mers; a lavatory reagent.
  • ShippingUN1760 Corrosive liquids, n.o.s., Hazard class: 8; Labels: 8-Corrosive material.
  • Purification MethodsDistil it from 3A molecular sieves, retaining the middle fraction. It has been prepared by reduction of hexafluoroacetone in tetrahydrofuran (THF), In this case hexafluoropropanol forms a stable 1:1 complex which distils at 99-100o/760mm (n 25 1.3283), The complex is decomposed by mixing with 20% oleum and distilling in a vacuum, and the distillate is redistilled to give pure hexafluoropropan-2-ol with b 59o/760mm. The 1H NMR shows a doublet at 4.52ppm (JH,H 2Hz). The benzoyl derivative, [10315-85-2] M 272.1, has m 53.9o after crystalllisation from pentane at -50o, and its IR has at 1760cm-1. [Middleton & Lindsey J Am Chem Soc 86 4948 1964, Urry et al. J Org Chem 32 347 1967.] It has very high peptide solubilising properties, alone or with CH2Cl2 [use as a solvent: Narita et al. Bull Chem Soc Jpn 61 281 1988, Biochemistry 29 2639 1990.] It is CORROSIVE, causes severe eye irritation.
  • IncompatibilitiesHFIP is incompatible with acids, acid chlorides, and oxidizing agents.
  • Waste DisposalMay be incinerated. In accor dance with 40CFR165, follow recommendations for the disposal of pesticides and pesticide containers. Must be dis posed properly by following package label directions or by contacting your local or federal environmental control agency, or by contacting your regional EPA office. Consult with environmental regulatory agencies for guidance on acceptable disposal practices. Generators of waste contain ing this contaminant (≥100 kg/mo) must conform to EPA regulations governing storage, transportation, treatment, and waste disposal.
