what is of DL-Mandelic acid with cas 90-64-2?
Mandelic acid is a high molecular weight fruit acid with lipophilicity. Compared with the common fruit acid glycolic acid, mandelic acid has a certain antibacterial ability. At the same time, compared to common glycolic acids and lactic acids, its transdermal speed will be slower, which means that the irritation is less than that of glycolic acids. Its fat solubility increases, and the transdermal ability of the stratum corneum is improved. Like glycolic acid and lactic acid, mandelic acid also has a certain whitening effect.

使用
DL-扁桃酸可能被用作一分析参考标准，用于确定DL-扁桃酸:
- 人尿液样本的高效液相色谱法(HPLC)装有紫外线(紫外线)探测器。
- 老鼠尿液样本通过气相色谱-质谱法(GC/MS)与选定的离子监测(SIM)检测。
