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 .
Bromobutane (molecular formula: C 4 H 9 Br, molar mass: 137.02 g/mol) may refer to either of two chemical compounds: 1-Bromobutane ( n -butyl bromide) 2-Bromobutane ( sec -butyl bromide or methylethylbromomethane)
The molecular formula C 4 H 9 Br, (molar mass: 137.02 g/mol, exact mass: 135.9888 u) may refer to: 1-Bromobutane; 2-Bromobutane; tert-Butyl bromide;
When the molecular weight is given with the unit Da, it is frequently as a weighted average similar to the molar mass but with different units. In molecular biology, the mass of macromolecules is referred to as their molecular weight and is expressed in kDa, although the numerical value is often approximate and representative of an average.
tert-Butyl bromide (also referred to as 2-bromo-2-methylpropane) is an organic compound with the formula Me 3 CBr (Me = methyl). The molecule features a tert-butyl group attached to a bromide substituent. This organobromine compound is used as a standard reagent in synthetic organic chemistry. It is a colorless liquid.
2 Li + C 4 H 9 X → C 4 H 9 Li + LiX where X = Cl, Br. The lithium for this reaction contains 1-3% sodium. When bromobutane is the precursor, the product is a homogeneous solution, consisting of a mixed cluster containing both LiBr and LiBu. 1-Fluorobutane can be obtained by reacting 1-bromobutane with potassium fluoride in ethylene glycol.

Tetrabutylammonium bromide can be prepared by the alkylation of tributylamine with 1-bromobutane. [2] Tetrabutylammonium bromide is used to prepare other salts of the tetrabutylammonium cation by salt metathesis reactions. [6] It serves as a source of bromide ions for substitution reactions. It is a commonly used phase transfer catalyst.
A molecular-weight size marker, also referred to as a protein ladder, DNA ladder, or RNA ladder, is a set of standards that are used to identify the approximate size of a molecule run on a gel during electrophoresis, using the principle that molecular weight is inversely proportional to migration rate through a gel matrix.
