3-Bromo-2-butanone

Description:

3-Bromo-2-butanone, with the CAS number 814-75-5, is an organic compound that belongs to the class of halogenated ketones. It features a four-carbon chain with a ketone functional group (C=O) located at the second carbon and a bromine atom attached to the third carbon. This compound is typically a colorless to pale yellow liquid with a characteristic odor. It is soluble in organic solvents such as ethanol and ether but has limited solubility in water due to its hydrophobic carbon chain. 3-Bromo-2-butanone is known for its reactivity, particularly in nucleophilic substitution reactions, where the bromine atom can be replaced by various nucleophiles. It is often used as an intermediate in organic synthesis, particularly in the preparation of pharmaceuticals and agrochemicals. Safety precautions should be taken when handling this compound, as it may pose health risks, including irritation to the skin and respiratory system. Proper storage in a cool, dry place away from light is recommended to maintain its stability.

3-Bromo-2-butanone

CAS: 814-75-5

3-Bromo-2-butanone is a chemical compound that has been detected in the lithosphere and is produced by the action of phosphorus pentoxide on brominated hydrocarbons. 3-Bromo-2-butanone can be used as an analog for acetaldehyde to study the effects of reactive species. It was found that 3-bromo-2-butanone reacts with phosphite in acetic acid to form a chlamydozonium ion and an acid catalyst, which leads to the formation of acetaldehyde. The reaction mechanism is shown below: 3BrCH=CHBr + P(O)OH → CH=CHCOH + H+ The overall reaction can be represented as: 3BrCH=CHBr + P(O)OH → CH=CHCOH + H+ HOAc + H+ → HOAc
