(2E)-1-Bromo-2-butene

Description:

(2E)-1-Bromo-2-butene is an organic compound characterized by its structure as a bromoalkene. It features a double bond between the second and third carbon atoms in a four-carbon chain, with a bromine atom attached to the first carbon. This compound is classified as a halogenated alkene, which contributes to its reactivity, particularly in nucleophilic substitution and elimination reactions. The presence of the double bond introduces geometric isomerism, with the (E) configuration indicating that the highest priority substituents on either side of the double bond are on opposite sides. (2E)-1-Bromo-2-butene is typically a colorless to pale yellow liquid at room temperature and has a relatively low boiling point compared to saturated hydrocarbons of similar molecular weight. It is soluble in organic solvents but has limited solubility in water. This compound is used in various chemical syntheses and can serve as an intermediate in the production of other organic compounds. Safety precautions should be taken when handling it, as it may pose health risks due to its bromine content.

trans-Crotyl bromide

CAS: 29576-14-5

Trans-crotyl bromide is a pharmaceutical preparation of the hydroxyl group. It is an allylation reagent that reacts with halides to form an organic compound with a new chemical function. Trans-crotyl bromide has been shown to inhibit the activity of inflammatory enzymes, such as kinases and proteases. This inhibition may be due to the release of reactive oxygen species from the active site or by blocking access to the active site. Trans-crotyl bromide also inhibits HIV-1 infection by interfering with viral protein synthesis, which may be due to its ability to bind to polyproteins and inhibit ribosome binding.
