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.

Utilizzo 

DL-acido Mandelico può essere utilizzato come un analitici standard di riferimento per la determinazione del DL-acido mandelico in:

  • Umana campioni di urina mediante cromatografia liquida ad alta prestazione (HPLC) dotate di raggi ultravioletti (UV) del rivelatore.
  • Ratto campioni di urina mediante gas-cromatografia-spettrometria di massa (GC-MS) con ioni selezionati di monitoraggio (SIM) di rilevamento.
