Products Description of (-)-(R)-Mandelic Acid CAS#611-71-2

D-mandelic acid is a polar molecule. Because it contains hydroxyl and carboxyl groups, the molecule has a certain degree of hydrophilicity. Since D-mandelic acid is a chiral molecule, its physical and chemical properties are affected by the stereostructure of its molecule. In addition, the acid-base properties of D-mandelic acid are also affected by the molecular structure. The acidity of its carboxyl group is weak because the hydroxyl group on the chiral carbon atom replaces a hydrogen atom, which reduces the resonance stability of the negative charge. From the perspective of chemical reactions, the chiral structure of D-mandelic acid also affects the chirality of its reaction products. This chiral property is of great significance in organic synthesis and can be used to prepare drugs and chemicals of chiral molecules.
