D-酒石酸

分析標(biāo)準(zhǔn)品,HPLC≥98%

D-Tartaric acid

CAS號：147-71-7

分子式：C4H6O6

分子量：150.09

MDL：MFCD00004238

別名：右旋酒石酸;2,3-二羥基丁二酸;葡萄酸;二羥基琥珀酸;D-2,3-二羥基琥珀酸;D-2,3-二羥基丁二酸

產(chǎn)品介紹

有二個不對稱碳原子，有四種立體異構(gòu)體，即：右旋型（D型， L型）、左旋型（L型，D型）、內(nèi)消旋型、外消旋型。通常，外消旋型酒石酸又稱為葡萄酸。右旋型酒石酸以游離的或K鹽、Ca鹽、Mg鹽的形態(tài)廣泛分布于高等植物中，特別是多存在于果實(shí)和葉中。等量右旋體和左旋體的混合物的旋光性相互抵消，稱為外消旋酒石酸。內(nèi)消旋體不存在于自然界中，可由化學(xué)合成。各種酒石酸都是易溶于水的無色結(jié)晶。

熔點(diǎn)：172-174 ℃

沸點(diǎn)：191.59℃ (rough estimate)

比旋光度：-12.1 o (C=20, H2O)

外觀：白色粉末或結(jié)晶

溶解性：可溶于水

敏感性：對光敏感

儲存條件：2-8℃
