C6H4ClNO2

C6H4ClNO2 is a chemical compound with the molecular formula C6H4ClNO2. It is a derivative of benzene, where one hydrogen atom has been replaced by a chlorine atom, one hydrogen atom by a nitro group (-NO2), and one hydrogen atom by an amino group (-NH2). This compound is often referred to as 2-amino-4-chloronitrobenzene.

The compound is typically a yellow to orange crystalline solid at room temperature. It is soluble in organic solvents such as ethanol and acetone, but insoluble in water. C6H4ClNO2 is commonly used in organic synthesis as a precursor to various pharmaceuticals and other organic compounds. Its reactivity is due to the presence of the nitro group, which can undergo various nucleophilic substitution reactions.

The compound can be synthesized through the nitration of 2-aminobenzyl chloride, followed by chlorination. The synthesis involves several steps, including the activation of the benzene ring and the selective substitution of hydrogen atoms.

C6H4ClNO2 is a hazardous substance and should be handled with care. It is classified as a potential carcinogen and can cause skin and eye irritation. Proper personal protective equipment and ventilation should be used when handling this compound. Additionally, it is important to dispose of C6H4ClNO2 waste according to local regulations to minimize environmental impact.
