CAS: 3438-16-2
分子式: C8H7ClO3
分子量: 186.60
熔点: 98-100℃
中文名称: 
5-氯-2-甲氧基苯甲酸
英文名称: 
5-Chloro-2-methoxybenzoic acid
5-chloro-o-anisic acid
性质描述: 熔点81-82℃。
生产方法: 水杨酸经氯化、甲基化而得。将水杨酸溶于氯苯中,在日光灯照射下,在55-80℃通氯。氯化结束,冷却,过滤,干燥,得5-氯水杨酸。将其加入氢氧化钠溶液中,搅拌下滴加硫酸二甲酯,并续加氢氧化钠溶液使反应液pH在10-12,保持温度在35℃以下。加毕,于26-35℃保温8h。趁热过滤,滤液用15%盐酸调节pH至2-3,放冷、过滤、洗涤、干燥得5-氯-2-甲氧基苯甲酸。
用途: 医药中间体。
