The rate of hydrolysis of the formyl moiety of cefamandolenafate was determined as a function of pH, temperature, and concentration of added sodium carbonate or tromethamine. The reaction rate was sensitive to hydroxide ion in the pH 5.5-8.0 range with half-life values of hours to minutes. Hydrolysis was rapid upon the addition of sodium carbonate or tromethamine.
