title: Kinetics and mechanism of the basic hydrolysis of indomethacin and related compounds: a reevaluation.
abstract: The kinetics of the hydrolysis of indomethacin and related compounds were studied in an alkaline medium at 25 degrees. The pseudo-first-order rate constants were evaluated from log absorbance versus time plots in the ultraviolet. These compounds showed a second-order rate constant at low concentrations of hydroxide ion and a first-order rate constant at higher concentrations of hydroxide ion.
