1-Ethyl-4-nitrobenzene, with the CAS number 100-12-9, is an organic compound characterized by a nitro group (-NO2) attached to a benzene ring that also bears an ethyl group (-C2H5) at the para position relative to the nitro substituent. This compound is typically a yellowish liquid or solid at room temperature and is known for its aromatic properties. It is moderately soluble in organic solvents but has limited solubility in water due to its hydrophobic ethyl group. 1-Ethyl-4-nitrobenzene is primarily used in organic synthesis and as an intermediate in the production of dyes, pharmaceuticals, and other chemical compounds. It exhibits typical electrophilic aromatic substitution reactivity, making it a valuable building block in synthetic organic chemistry. However, it is important to handle this compound with care, as nitro compounds can be hazardous, posing risks such as toxicity and environmental concerns. Proper safety measures should be observed when working with this substance in laboratory or industrial settings.

4-Ethylnitrobenzene

4-Ethylnitrobenzene is an organic compound that has resonance mass at 289.14 g/mol. It is a colorless liquid with a boiling point of 213°C and a melting point of -7°C. The molecule has two geometric isomers, which are distinguished by the position of the methyl group on the benzene ring. 4-Ethylnitrobenzene can be produced by treating nitric acid with an alcohol in a hydrochloric acid solution or by heating sodium hydroxide and nitrobenzene in an organic solvent. The reaction rate for this reaction is controlled by the activation energy for hydrogen abstraction from the hydroxide ion to produce water and a positively charged nitronium ion (NO+) as well as the concentration of reactants. The reaction rate also depends on the type of metalloporphyrin used as catalyst and the pressure applied to it.
