Chemische Eigenschaften

white to light yellow crystal powde

Verwenden

(R)-(-)-Mandelic acid, is used as a antiseptic ingredient particularly against urinary tract infections.Mandelic acid and its derivatives are used to apply the dual activities as an antibacterial agent and as an antiaging agent. It is used as an intermediate for the synthesis of target molecules for other applications.

Allgemeine Beschreibung

(R)-(-)-Mandelic acid, a chiral resolving agent, is also used as a building block to synthesize pharmaceutical drugs such as penicillin and cephalosporin. It can be synthesized from (R,S)-mandelonitrile with high yield and enantioselectivity using nitrilase enzyme.

l?uterung methode

Purify the mandelic acids by recrystallisation from H2O, *C6H6 or CHCl3. [Roger J Chem Soc 2168 1932,Jamison & Turner J Chem Soc 611 1942.] They have solubilities in H2O of ca 11% at 25o. [Banks & Davies J Chem Soc 73 1938.] The S-benzylisothiuronium salts has m 180o (from H2O) and [] D 25 (+) and (-) 57o (c20, EtOH) [El Masri et al. Biochem J 68 199 1958]. [Beilstein 10 IV 564.]
