CF4CH2OH 100.04 CAS RN®: 75-89-8.—Colorless liquid.
Assay: Inject an appropriate specimen into a gas chromatograph (see Chromatography 〈621〉) equipped with a flame-ionization detector, helium being used as the carrier gas. The following conditions have been found suitable: a 0.25-mm × 30-m capillary column coated with a 1-μm layer of phase G2; the injection port temperature is maintained at 100°; the detector temperature is maintained at 150°; and the column temperature is maintained at 0° and programmed to rise 10° per minute to 150°. The area of the CF4CH2OH peak is not less than 99% of the total peak area.
Boiling Range: between 77° and 80°.
