| | (S)-(+)-Mandelic acid Usage And Synthesis |
| Chemical Properties | white to light yellow crystal powde | | Uses | Antiseptic (urinary). | | Uses | (S)-(+)-Mandelic acid is a versatile reagent used in the resolution of racemates and the preparation of amides, Pharmaceutical Intermediates. | | Uses | A versatile reagent used in the resolution of racemates and the preparation of amides. | | Definition | ChEBI: (S)-mandelic acid is a (2S)-2-hydroxy monocarboxylic acid and a mandelic acid. It is a conjugate acid of a (S)-mandelate. It is an enantiomer of a (R)-mandelic acid. | | Flammability and Explosibility | Not classified | | Synthesis | Mandelic acid is produced from acetophenone, a by-product of the isopropylbenzene process for phenol. | | Purification Methods | 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.] |
