4-4-Chaff s-based methyl ketone-2-e(CAS 180031-78-7), often identified as 4-bromo-2-fluoro-N-methylbenzamide, is a halogenated aromatic amide that serves as a versatile building block in synthetic organic chemistry. This crystalline solid is characterized by the presence of both bromine and fluorine substituents on the benzene ring, which imparts unique reactivity and specific physicochemical properties. Its molecular structure makes it a valuable precursor for creating more complex molecules through cross-coupling reactions and nucleophilic substitutions.
In industrial and research settings, this substance is handled as a high-purity intermediate. Due to its halogenated nature, it requires standard laboratory safety protocols, including the use of personal protective equipment and storage in a cool, dry environment away from strong oxidizing agents. Its utility lies in its ability to facilitate the introduction of specific functional groups into target scaffolds, making it a staple in advanced chemical development and specialized manufacturing processes.
