Dextrose 葡萄糖 C 6H 12O 6·H 2O D -Glucose, monohydrate. D -Glucose monohydrate [ 5996-10-1 ]. Anhydrous [ 50-99-7 ]. C 6H 12O 6·H 2O 分子量: C 6H 12O 6 分子量: ? Dextrose isa sugar usually obtained by the hydrolysis of starch. It contains one molecule of water of hydration or is anhydrous. 葡萄糖是淀粉水解而得到的一种糖,常以一水葡萄糖或无水葡萄糖的形式存在。 Packaging and storage — Preserve in well-closed containers. 包装与贮存:本品保存在密闭容器中。 Labeling — Label it to indicate whether it is hydrous or anhydrous. 注释:注明其为无水状态或水合物状态。 Identification — Add a few drops ofa solution (1 in 20) to5 mL of hot alkaline cupric tartrate TS: a copious red precipitate of cuprous oxide is formed. 鉴别: 加本品溶液( 1比 20 )数滴于 5mL 热的碱性酒石酸铜试剂中,会形成大量红色的氧化亚铜沉淀。 Color of solution — Dissolve 25 g in water to make mL of solution: the solution has no more color than a solution prepared by mixing mL of cobaltous chloride CS, mL of ferric chloride CS, and mL of cupric sulfate CS with water to make 10 mL, and diluting 3 mL of this solution with water to 50 mL. Make parison by viewing the solutions downward in matched parison tubes against a white surface. 溶液颜色: 取本品 25g , 用水溶解配制成 50mL 的溶液, 该溶液颜色不得深于对照液颜色(将 ***化钴溶液、 ***化铁溶液和 硫酸铜溶液混匀后用水配制成 10mL ,取 3mL 该溶液用水稀释至 50mL 即得到对照液) 。通过在白色背景下观察溶液下流至相应比色管来进行颜色对比分析。 Specific rotation 781S : between + and + . Test solution: 100 mg per mL, in N ammonium hydro
