The rate of hydrolysis of the formyl moiety of cefamandole nafate 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. Chirality in the 7-D-mandelamido
根据pH,温度和加入的碳酸钠或三甲胺的浓度来确定头孢曼陀烷萘甲酸酯的甲酰基部分的水解速率。反应速率对pH 5.5-8.0范围内的氢氧根离子敏感,半衰期为数小时至数分钟。加入碳酸钠或氨丁三醇后,水解迅速。7-D-曼德拉米多侧链中的手性不受水解影响。
