4-Nitro-o-xylene

Description:

4-Nitro-o-xylene, also known as 4-nitro-1,2-dimethylbenzene, is an aromatic compound characterized by the presence of a nitro group (-NO2) and two methyl groups (-CH3) attached to a benzene ring. The nitro group is positioned at the para position relative to one of the methyl groups, while the other methyl group is located at the ortho position. This compound typically appears as a yellow crystalline solid and is sparingly soluble in water but more soluble in organic solvents such as ethanol and ether. It has a relatively high melting point and exhibits stability under standard conditions. 4-Nitro-o-xylene is primarily used in organic synthesis and as an intermediate in the production of dyes, pharmaceuticals, and other chemical compounds. Due to the presence of the nitro group, it may exhibit some degree of toxicity and should be handled with care, following appropriate safety protocols. Its chemical behavior is influenced by the electron-withdrawing nature of the nitro group, which can affect reactivity in electrophilic aromatic substitution reactions.
