C6H4ClNO3

C6H4ClNO3 is the molecular formula for several chemical compounds, most notably nitrochlorobenzene derivatives. This formula indicates a benzene ring (C6H4) substituted with a chlorine atom (Cl), a nitro group (NO2), and another group, likely an oxygen-containing functional group such as a hydroxyl (OH) or a carboxyl (COOH), to satisfy the valency. However, without a specific structural arrangement, multiple isomers are possible.

One significant compound with this formula is 2-chloro-5-nitrobenzoic acid, a derivative of benzoic acid. This compound is a crystalline solid and can be synthesized through the nitration of 2-chlorobenzoic acid. Its applications are often found in organic synthesis as a building block for more complex molecules, potentially in the pharmaceutical or agricultural industries.

Another possibility is a nitrophenol derivative, such as 4-chloro-3-nitrophenol. This compound, like many nitrophenols, can exhibit acidic properties due to the electron-withdrawing nitro group. It might be used as an intermediate in the production of dyes, pesticides, or other specialty chemicals. The exact properties and uses of a compound with the formula C6H4ClNO3 are entirely dependent on the specific arrangement of the atoms, defining its unique isomer.
