1-Bromobutane is the precursor to n-butyllithium: [4] 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.
Risk and Safety Statements, also known as R/S statements, R/S numbers, R/S phrases, and R/S sentences, is a system of hazard codes and phrases for labeling dangerous chemicals and compounds. The R/S statement of a compound consists of a risk part (R) and a safety part (S), each followed by a combination of numbers. Each number corresponds to a ...
In the European Union, 1-bromopropane has been classified as reproductive toxicant per Registration, Evaluation, Authorisation and Restriction of Chemicals, which makes it a "substance of very high concern". [12] As of January 5, 2022, 1-bromopropane has been added to the United States Clean Air Act list of Hazardous Air Pollutants (HAP). [13]
They have the formula C 5 H 12–n Br n, where n = 1–12 is the number of bromine atoms. They are colorless liquids. ... Bromobutane; Bromohexane; References This ...

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.
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)
Use of the TC-14G canister schedule or the TC-23C chemical cartridge schedule for a given respirator depends on whether "acid gas" is a designated contaminant, which is designated for gas mask canisters only, or if the manufacturer is obligated to list all designated contaminants supported by a given chemical cartridge.
