Products Description of (S)-(+)-Mandelic Acid 99% CAS#17199-29-0
(S)-(+)-Mandelic acid appears as a white, lustrous crystalline powder, crystals or flakes. It exhibits a water solubility of 100 g/L at 25 °C and is also soluble in alcohols and ethers. It has a melting point of 134 °C, a specific rotation of 155° (c = 2, H₂O) and a refractive index of 153.5° (c = 1, H₂O). As an important raw material, it is used for the synthesis of (S)-cyclohexenyl phenyl glyoxylic acid, which is the optically active tertiary α-hydroxy acid moiety in (S)-oxybutynin. Furthermore, it is a versatile reagent widely applied in racemate resolution and amide synthesis.
