分子式:
CAS号:

性质:又称对映异构(enantiometry isomerism),镜像异构(mirror image isomerism)或光学异构。立体异构中的一种。两个异构体是有相同的物理和化学性质,但对偏振光旋转方式不同而产生的异构现象。偏振光的平面一个为右旋,另一个为左旋,分别称为右旋或左旋(d或l)异构体。左右旋异构体虽然使偏振光旋转方向不同,但是旋转程度相等。含有相同浓度两种异构体的溶液旋光性彼此抵消,这样的右旋和左旋混合物称为外消旋混合物。旋光异构体的空间结构是像实物和镜像或左手和右手的关系,彼此互相是对映体,但不能互相重叠(即手性分子)。在含有双齿配体的八面体配位化合物中旋光异构现象是常见的。旋光异构现象主要存在于含碳化合物中。有时对映体的生理作用有极大差异,对研究生命科学有重要意义。
