摘要:
The invention is relative to a thioctic acid with a predominant amount of an enantiomer and a novel modification, in the case of which the X-ray powder diffractograms show a characteristic reflex in the range of 23.4 to 22.7.degree. 2 theta(Cu) which shifts in the direction of the smaller angular values as the enantiomer content increases.
