3′-Methoxypropiophenone, identified by CAS number 37951-49-8, is an aromatic ketone characterized by a methoxy group attached to the meta-position of the phenyl ring relative to the propanoyl substituent. This specific substitution pattern provides unique electronic and steric properties compared to its ortho or para isomers, making it a valuable building block in fine chemical synthesis. As a clear to pale yellow liquid or low-melting solid, it serves as a versatile precursor for the construction of more complex organic molecules.
In industrial and research settings, this compound is handled with standard laboratory precautions, requiring storage in cool, dry conditions away from strong oxidizing agents. Its chemical reactivity is primarily centered on the carbonyl group and the activated aromatic ring, allowing for a variety of transformations including reductions, nucleophilic additions, and electrophilic aromatic substitutions. This adaptability ensures its continued relevance in the development of specialty chemicals and advanced materials.
