4-Chloro-3-nitrocinnamic acid

Description:

4-Chloro-3-nitrocinnamic acid is an organic compound characterized by its aromatic structure, which includes a cinnamic acid backbone substituted with both a chlorine and a nitro group. The presence of the chloro group at the 4-position and the nitro group at the 3-position on the phenyl ring significantly influences its chemical properties, including its reactivity and solubility. This compound typically appears as a yellow crystalline solid and is known for its potential applications in organic synthesis and as an intermediate in the production of various pharmaceuticals and agrochemicals. It exhibits moderate solubility in organic solvents and limited solubility in water, which is common for many aromatic compounds. The presence of both electron-withdrawing groups (the nitro and chloro substituents) enhances its acidity compared to unsubstituted cinnamic acid. Additionally, 4-Chloro-3-nitrocinnamic acid can participate in various chemical reactions, including nucleophilic substitutions and coupling reactions, making it a valuable compound in synthetic organic chemistry.

4-Chloro-3-nitrocinnamic acid is a thionyl chloride derivative of cinnamic acid. It is used as an intermediate in the preparation of pharmaceuticals and dyestuffs. 4-Chloro-3-nitrocinnamic acid inhibits the activity of amides, dimethylformamide, alkaline hydrolysis, xylene, carboxyphenyl, cinnamic, refluxing, nitrophenyl and carboxylic acids. 4-Chloro-3-nitrocinnamic acid reacts with chloride to form the corresponding chloride salt. This compound can also react with formamide to form an amide salt. The ester group of 4-chloro-3-nitrocinnamic acid can be cleaved by nitro compounds to produce nitro derivatives.
