3-Methyl-2-butenoyl chloride

Description:

3-Methyl-2-butenoyl chloride, with the CAS number 3350-78-5, is an organic compound characterized by its acyl chloride functional group, which makes it a reactive intermediate in organic synthesis. It features a four-carbon chain with a double bond and a methyl substituent, contributing to its unsaturation and reactivity. This compound is typically a colorless to pale yellow liquid with a pungent odor, indicative of its reactivity and potential for hydrolysis in the presence of moisture, forming the corresponding acid. It is soluble in organic solvents such as ether and dichloromethane but reacts with water, making it less stable in aqueous environments. 3-Methyl-2-butenoyl chloride is primarily used in the synthesis of various chemical compounds, including pharmaceuticals and agrochemicals, due to its ability to introduce acyl groups into other molecules. Safety precautions are essential when handling this compound, as it can be corrosive and irritating to the skin, eyes, and respiratory system. Proper storage in a cool, dry place away from moisture is recommended to maintain its stability.
