A specialty solvent for some poly mers; a lavatory reagent. | [Fire Hazard]
This chemical is probably combustible. | [First aid]
Move victim to fresh air. Call 911 or emergency
medical service. Give artificial respiration if victim is not
breathing. Do not use mouth-to-mouth method if victim
ingested or inhaled the substance; give artificial respira tion with the aid of a pocket mask equipped with a one-way
valve or other proper respiratory medical device.
Administer oxygen if breathing is difficult. Remove and
isolate contaminated clothing and shoes. In case of contact
with substance, immediately flush skin or eyes with running water for at least 20 minutes. For minor skin con tact, avoid spreading material on unaffected skin. Keep vic tim warm and quiet. Effects of exposure (inhalation,
ingestion or skin contact) to substance may be delayed.
Ensure that medical personnel are aware of the material(s)
involved and take precautions to protect themselves.
Medical observation is recommended for 24 to 48 hours
after breathing overexposure, as pulmonary edema may be
delayed. As first aid for pulmonary edema, a doctor or
authorized paramedic may consider administering a drug or
other inhalation therapy. | [Shipping]

1,1,1,3,3,3-Hexafluoro-2-propanol is a solution-phase peptide chemistry solvent. This fluorinated polar solvent of high ionizing power facilitates Friedel–Crafts-type reactions, using covalent reagents in the absence of a Lewis acid catalyst. It also enhances the efficiency of rhodium(I)-catalyzed [4+2] intramolecular cycloaddition of ether-tethered alkynyl dienes and [5+2] cycloaddition of alkynyl vinylcyclopropanes. 1,1,1,3,3,3-Hexafluoro-2-propanol clusters catalyzes the epoxidation of cyclooctene and 1-octene with hydrogen peroxide. | [storage]

Distil 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.

| Questions And Answer | Back Directory | [Description]
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. | [Clinical application]
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. | [Hazards]
