Hydrolysis with diclofenac acids
Web8 dec. 2024 · Hydrolysis may be considered the reverse of a condensation reaction, in which two molecules combine with each other, producing water as one of the products. Origin: The term comes from the Greek prefix hydro - (water) and lysis (to break apart). General formula of a hydrolysis reaction is: AB + H 2 O → AH + BOH WebAbstract An HPLC method for the determination of diclofenac (DCF) and four of its metabolites (3'-hydroxydiclofenac, 4'-hydroxydiclofenac, 5-hydroxydiclofenac, and 3'-hydroxy-4'-methoxydiclofenac) in human urine is described. Following base hydrolysis, the samples were neutralized and extracted.
