2-Bromopropane, also known as isopropyl bromide and 2-propyl bromide, is the halogenated hydrocarbon with the formula CH 3 CHBrCH 3. It is a colorless liquid. It is a colorless liquid. It is used for introducing the isopropyl functional group in organic synthesis . 2-Bromopropane is prepared by heating isopropanol with hydrobromic acid .
2-Bromobutane is an isomer of 1-bromobutane. Both compounds share the molecular formula C 4 H 9 Br. 2-Bromobutane is also known as sec-butyl bromide or methylethylbromomethane. Because it contains bromine, a halogen, it is part of a larger class of compounds known as alkyl halides. It is a colorless liquid with a pleasant odor.
1,2-Dibromopropane, also known as propylene dibromide, is an organic compound with the formula CH 3 CHBrCH 2 Br. It is the simplest chiral hydrocarbon containing two bromine atoms: ( S )-1,2-Dibrompropane (above) and ( R )-1,2-Dibrompropane (below)
Organolithium reagent. In organometallic chemistry, organolithium reagents are chemical compounds that contain carbon – lithium (C–Li) bonds. These reagents are important in organic synthesis, and are frequently used to transfer the organic group or the lithium atom to the substrates in synthetic steps, through nucleophilic addition or ...
Chirality (chemistry) Two enantiomers of a generic amino acid that are chiral. (S)-Alanine (left) and (R)-alanine (right) in zwitterionic form at neutral pH. In chemistry, a molecule or ion is called chiral (/ ˈkaɪrəl /) if it cannot be superposed on its mirror image by any combination of rotations, translations, and some conformational changes.
Chiral column chromatography[1][2] is a variant of column chromatography that is employed for the separation of chiral compounds, i.e. enantiomers, in mixtures such as racemates or related compounds. The chiral stationary phase (CSP) is made of a support, usually silica based, on which a chiral reagent or a macromolecule with numerous chiral ...
Chiral analysis refers to the quantification of component enantiomers of racemic drug substances or pharmaceutical compounds. Other synonyms commonly used include enantiomer analysis, enantiomeric analysis, and enantioselective analysis. Chiral analysis includes all analytical procedures focused on the characterization of the properties of ...
Supercritical fluid chromatography (SFC) [1] is a form of normal phase chromatography that uses a supercritical fluid such as carbon dioxide as the mobile phase. [2] [3] It is used for the analysis and purification of low to moderate molecular weight, thermally labile molecules and can also be used for the separation of chiral compounds.
