(S +)-邻氯苯甘氨酸甲酯酒石酸盐 (S)-(+)-2-chlorophenylglycine methyl ester tartrate Explanation: http://www.chempacific.com/servlet/ChempacUserv (S +)-邻氯苯甘氨酸甲酯酒石酸盐 = (S)-(+)-2-chlorophenylglycine methyl ester [CAS 141109-14-0] C9H10ClNO2 tartrate 酒石酸盐 -------------------------------------------------- Note added at 1 hr 11 mins (2004-04-02 04:35:00 GMT) -------------------------------------------------- For (S)-(+)-2-chlorophenylglycine methyl ester [CAS 141109-14-0], see Catalog ID 10380 at this webpage: http://www.chempacific.com/servlet/ChempacUserv -------------------------------------------------- Note added at 4 hrs 33 mins (2004-04-02 07:56:55 GMT) Post-grading -------------------------------------------------- Jianming, 甘氨酸也就是氨基乙酸,其分子中有一个氨基。在我提供的那个webpage上Catalog ID 10380 的旁边有一个分子式C9H10ClNO2。你点击该分子式就可看到那个氨基。该氨基可以与酸根结合而形成盐。因此,所谓的酒石酸盐是酒石酸与(S)-(+)-邻氯苯甘氨酸甲酯中的氨基形成的盐,而不是与其甲酯形成的盐。凡是氨基酸都具有这种性质。 老弟:你简直是在考我。这都是我40年前学的东西,幸好还没完全还给老师。但你总有一天会把我考倒、“烤糊”。不过我很欣赏你的钻研精神。我原来以为你会问我(S)-(+)是什么意思。现在我也拿这一问题考考你,如何? -------------------------------------------------- Note added at 4 hrs 41 mins (2004-04-02 08:05:33 GMT) Post-grading -------------------------------------------------- (S +)-邻氯苯甘氨酸甲酯 = (S)-(+)-2-chlorophenylglycine methyl ester Reference: http://www.chempacific.com/servlet/ChempacUserv |
