D-对羟基苯甘氨酸是一种白色片状结晶或白色结晶粉末,熔点为204℃(分解),微溶于乙醇和水,易溶于酸或碱溶液生成盐。
用途与氢氧化钾、氢氧化钠反应可得邓钾盐和邓钠盐,后者是制备半合成青霉素羟氨苄青霉素(即阿莫西林)和头孢类抗生素头孢羟氨苄(商品名欧意)、头孢哌酮等的重要侧链化合物。还可生产羟氨苄唑头孢、头孢罗齐、头孢曲嗪等,因其用途广且合成的医药产品既可注射又可口服,临床疗效优于氨苄西林。
用途主要用于制造半合成抗生素阿莫西林。
用途用作医药中间体,主要用于半合成青霉素、羟氨苄青霉素、头孢菌素等药物合成。
用途有机、医药合成中间体,可用于合成羟氨苄青霉素(即阿莫西林)、羟氨苄头孢霉素等抗菌素药物。
生产方法大茴香醛经环合、水解制成DL-对羟基苯甘氨酸,再用甲醇酯化,用酒石酸拆分,得到D(-)-对羟基苯甘氨酸。国内大部分D-对羟基苯甘氨酸的生产企业目前基本都采用乙醛酸工艺生产。
