3-Fluoronitrobenzene（Cat No.:R040227）is an aromatic compound featuring a fluorine atom and a nitro group attached to a benzene ring. It typically appears as a pale yellow liquid and is commonly used as an intermediate in organic synthesis, especially for agrochemicals, dyes, and pharmaceuticals. The fluorine substitution alters the reactivity of the aromatic ring, making it a useful building block in the preparation of more complex fluorinated aromatic compounds. Due to the nitro group, it requires careful handling and is usually processed under controlled conditions in research and industrial environments.
