补充资料:DBM
分子式:C6H12Br2O4
分子量:307.97
CAS号:10318-26-0
性质:白色结晶或结晶性粉末。熔点187-188℃(分解)。易溶于浓氢溴酸及DMF,略溶于乙醇,微溶于水和酮。遇碱易分解,其水溶液能分解逸出氢溴酸。在干燥空气中稳定,无臭,味微苦。
制备方法:由D-甘露醇与氢溴酸反应得到二溴甘露醇。将甘露溶解于氢溴酸,加热回流3h。加水稀释并降温至52℃,加入活性炭脱色。过滤,将滤液降温至20℃,搅拌下用碳酸氢钠调节pH至1-2,冷冻后甩滤、水洗、氯仿洗,真空干燥后用甲醇重结晶、活性炭脱色精制而得成品。收率约36%。
用途:本品为抗肿瘤药物。大鼠口服LD50为1400mg/kg。
