4-Nitrobenzaldeide

Descrizione:

4-Nitrobenzaldeide, con il numero CAS 555-16-8, è un aldeide aromatica caratterizzata dalla presenza di un gruppo nitro (-NO2) posizionato nella posizione para rispetto al gruppo aldeidico (-CHO) su un anello di benzene. Questo composto appare tipicamente come un solido cristallino giallo e ha un odore aromatico distintivo. È solubile in solventi organici come etanolo ed etere, ma ha una solubilità limitata in acqua a causa della sua struttura aromatica idrofobica. 4-Nitrobenzaldeide è noto per la sua reattività, in particolare nelle reazioni di sostituzione elettrofila aromatica e come precursore nella sintesi di vari composti organici, inclusi farmaci e agrochimici. Il gruppo nitro aumenta l'elettronegatività dell'anello aromatico, rendendolo un intermedio utile nella chimica organica sintetica. Inoltre, presenta un certo grado di tossicità e deve essere maneggiato con cura, seguendo i protocolli di sicurezza appropriati. Le sue applicazioni si estendono alla ricerca nella scienza dei materiali e come reagente in varie reazioni chimiche.

4-Nitrobenzaldehyde is a reactive compound that has been shown to have antimicrobial activity. It is used in the synthesis of antibiotics and other pharmaceuticals. 4-Nitrobenzaldehyde binds to the mitochondrial membrane potential, which leads to the disruption of aerobic respiration. This compound has also been shown to bind to human serum proteins, such as albumin. The mechanism of this binding is through hydrogen bonding interactions with the amine groups on the protein surface. The reaction of 4-nitrobenzaldehyde with sodium carbonate results in an equilibrium between nitrobenzene and 4-nitrophenol. The equilibrium constant for this reaction can be determined experimentally by measuring the solubility of these compounds at different concentrations.
4-Nitrobenzaldehyde can be used as a model system for studying electron transfer reactions in electrochemistry through its interaction with methyl ethyl ketone (MEK) and pyridine (PYR). MEK
