Bromopyruvic acid is the organic compound with the formula BrCH 2 COCO 2 H. This colorless solid is the brominated derivative of pyruvic acid. It bears structural similarity to lactic acid and pyruvic acid. It has been investigated as a metabolic poison and an anticancer agent. [1] Like other α-bromoketones, it is a strong alkylating agent.
Ethyl 3-bromopropionate is the organobromine compound with the formula BrCH 2 CH 2 CO 2 C 2 H 5. It is a colorless liquid and an alkylating agent. It is prepared by the esterification of 3-bromopropionic acid. [1] Alternatively, it can be prepared by hydrobromination of ethyl acrylate, a reaction that proceeds in an anti-Markovnikov sense. [2]
4-Bromophenylacetic acid may be prepared by the addition of a bromine atom to phenylacetic acid through electrophilic aromatic substitution.It was first prepared in the laboratory by treatment of phenylacetic acid with bromine and mercuric oxide; a mixture of the 2- and 4- isomers is made, and the 4- isomer is isolated by fractional crystallization.
An example of the Hell–Volhard–Zelinsky reaction can be seen in the preparation of alanine from propionic acid.In the first step, a combination of bromine and phosphorus tribromide is used in the Hell–Volhard–Zelinsky reaction to prepare 2-bromopropionic acid, [3] which in the second step is converted to a racemic mixture of the amino acid product by ammonolysis.
2-Bromopentane [1] (chiral) 3-Bromopentane; There are four isomers of monobromopentane based on 2-methylbutane: 1-Bromo-2-methylbutane (chiral) 1-Bromo-3-methylbutane; 2-Bromo-2-methylbutane; 2-Bromo-3-methylbutane (chiral) 2,2-Dimethylpropane has only one monobrominated derivative, 1-bromo-2,2-dimethylpropane, also known as neopentyl bromide. [2]
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.
[3] Bromobenzene is used to introduce a phenyl group into other compounds. One method involves its conversion to the Grignard reagent, phenylmagnesium bromide. This reagent can be used, e.g. in the reaction with carbon dioxide to prepare benzoic acid. [4] Other methods involve palladium-catalyzed coupling reactions, such as the Suzuki reaction.
Though symptoms of overexposure can begin within 2 days of exposure, typically long-term exposure is more harmful. [ 8 ] In 2008, the U.S. CDC recommended that use of 1-bromopropane as a replacement for perchloroethylene may require adjustment and modification of equipment, improved ventilation, and use of personal protective equipment .
