Esteri e Derivati
Gli esteri sono composti organici formati dalla reazione di un acido (solitamente un acido carbossilico) con un alcol, con rilascio di acqua durante il processo. La loro struttura chimica include un gruppo funzionale -COO-, in cui un atomo di carbonio è legato a un gruppo ossigeno e a un gruppo alchilico o arilico. Gli esteri hanno un'ampia varietà di applicazioni industriali, tra cui solventi, fragranze, aromi e prodotti farmaceutici. In ambito farmacologico, alcuni esteri sono utilizzati come profarmaci, poiché la loro struttura consente un rilascio controllato o una maggiore biodisponibilità dei principi attivi.
Presso CymitQuimica, offriamo esteri e i loro derivati per la ricerca in chimica organica, formulazione farmaceutica e applicazioni industriali.
