Acido 4-nitrobenzoico

Descrizione:

Acido 4-nitrobenzoico è un acido carbossilico aromatico caratterizzato da un gruppo nitro (-NO2) posizionato nella posizione para rispetto al gruppo acido carbossilico (-COOH) su un anello benzenico. La sua formula molecolare è C7H5NO4 e ha un peso molecolare di circa 167,12 g/mol. Questo composto appare tipicamente come un solido cristallino giallo ed è scarsamente solubile in acqua, ma più solubile in solventi organici come etanolo e acetone. Acido 4-nitrobenzoico è noto per il suo utilizzo nella sintesi organica, in particolare come reagente nella preparazione di vari composti chimici, inclusi coloranti e prodotti farmaceutici. Mostra proprietà acide, con un valore di pKa che indica la sua capacità di donare protoni in soluzione. Inoltre, può subire varie reazioni chimiche, come nitrificazione e riduzione, rendendolo un intermedio versatile nella chimica sintetica. Devono essere adottate precauzioni di sicurezza quando si maneggia questo composto, poiché può essere dannoso se ingerito o inalato e può causare irritazione della pelle e degli occhi.

P-Nitrobenzoic acid

CAS: 62-23-7

P-Nitrobenzoic acid is a nitro compound that is used as an intermediate in the synthesis of various pharmaceuticals. It is also used in wastewater treatment to remove protocatechuic acid, which is produced during the oxidation of phenols by peroxidase. P-Nitrobenzoic acid can be synthesized by reacting sodium nitrite with p-hydroxybenzoic acid. The structure of this compound was determined through a series of experiments, and it was found that it has two nitrogen atoms that are incorporated into the benzene ring. This compound reacts with aziridine in an exothermic reaction mechanism to form an unstable five membered ring. This reaction proceeds through a series of steps and eventually forms p-nitrobenzoic acid.
