4-Methoxybenzeneacetyl chloride

Description:
4-Methoxybenzeneacetyl chloride, also known as p-methoxybenzoyl chloride, is an organic compound characterized by the presence of both an acetyl chloride functional group and a methoxy group attached to a benzene ring. Its molecular structure features a benzene ring substituted at the para position with a methoxy group (-OCH₃) and an acyl chloride group (-COCl). This compound is typically a colorless to pale yellow liquid with a pungent odor, indicative of its reactivity. It is soluble in organic solvents such as dichloromethane and ether but is generally insoluble in water due to the hydrophobic nature of the aromatic ring. 4-Methoxybenzeneacetyl chloride is primarily used in organic synthesis, particularly in the preparation of various pharmaceuticals and agrochemicals, where it serves as an acylating agent. Due to the presence of the acyl chloride functional group, it is reactive towards nucleophiles, making it useful in acylation reactions. Proper handling and storage are essential, as it can be corrosive and may release hydrochloric acid upon hydrolysis.
