CAS 1117-71-1: Methyl 4-bromo-2-butenoate

Description: Methyl 4-bromo-2-butenoate is an organic compound characterized by its structure, which features a bromine atom and an ester functional group. It is classified as a bromoalkene due to the presence of a double bond between the second and third carbon atoms in the butenoate chain. This compound typically appears as a colorless to pale yellow liquid with a distinctive odor. It is soluble in organic solvents such as ethanol and ether but has limited solubility in water due to its hydrophobic characteristics. Methyl 4-bromo-2-butenoate is known for its reactivity, particularly in nucleophilic substitution and addition reactions, making it a valuable intermediate in organic synthesis. It can be used in the preparation of various pharmaceuticals and agrochemicals. Safety precautions should be taken when handling this compound, as it may pose health risks, including irritation to the skin and eyes, and potential toxicity if ingested or inhaled. Proper storage in a cool, dry place away from incompatible substances is essential to maintain its stability.
