Description: Chloroform is a common laboratory reagent favored for use as a solvent due to the compounds relative unreactivity and miscibility with most organic compounds. Chloroform is a colorless, volatile chlorinated organic solvent whose vapors have a narcotic effect.
Chloroform is use as a solvent for fats, oils, rubber, alkaloids, waxes, gutta-percha, resins; as cleansing agent; in fire extinguishers to lower the freezing temperature of carbon tetrachloride. Procedures have been described for the use of chloroform in lambda plaques storage, lambda cDNA storage, the removal of mineral oil from PCR reaction samples, oligonucleotide purification, a hydroxyl radical footprinting protocol, a transcriptional run-on assay protocol, and an overlay assay for beta-galactosidase activity. It has also been used with phenol in such procedures as DNA recovery from polyacrylamide gels, ethidium bromide removal from DNA preparations, lysis protocols for plasmid DNA isolation, RNase removal, and purification of yeast DNA. A protocol describes the use of chloroform in a high-performance thin-layer chromatography protocol for sphingomyelin analysis. Chloroform can also be used in chloroform/methanol mixtures for the isolation of cardiolipids from Geobacillus stearothermophilus and their subsequent MS analysis. The isolation of the bacteriocin amylovorin L471 from Lactobacillus amylovorus DCE 471 in culture broth has been reported, using chloroform/methanol extraction and precipitation in the procedure. Chloroform/2-butanol mixtures can be used for the extraction of steroid sulfates for analysis by nanoelectrospray ionization mass spectrometry.

Description: 1,1,1,3,3,3-Hexafluoro-2-propanol is polar and exhibits strong hydrogen bonding properties enabling it to dissolve substances that serve as hydrogen-bond acceptors. 1,1,1,3,3,3-Hexafluoro-2-propanol is a polar solvent of high ionizing power and facilitates Friedel–Crafts-type reactions, using covalent reagents in the absence of a Lewis acid catalys. 1,1,1,3,3,3-Hexafluoro-2-propanol clusters catalyzes the epoxidation of cyclooctene and 1-octene with hydrogen peroxide.
It is a speciality solvent effective for solubilizing a wide range of polymers, including those that are not soluble in the most common organic solvents: such as polyamides, polyacrylonitriles, polyacetals, polyesters (e.g. polyglycolide), and polyketones. It has also found use in biochemistry to solubilize peptides and to monomerize β-sheet protein aggregates. It can be used as an acid in volatile buffers for ion pair HPLC - mass spectrometry of nucleic acids. 1,1,1,3,3,3-Hexafluoro-2-propanol was used for preparing hexafluoroalcohol-functionalized methacrylate polymers for lithographic/nanopatterning materials.
