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

Products Description of DL-Mandelic acid 99% CAS#90-64-2Mandelic acid is a large molecular weight fruit acid that is lipophilic. Compared with the common fruit acid-glycolic acid, mandelic acid has certain antibacterial ability. At the same time, compared with common glycolic acid and lactic acid, its penetration rate into Chemicalbook skin will be slower, which means that it is less irritating than glycolic acid. Its fat solubility is increased and the ability of stratum corneum to penetrate the skin is improved.

Products Description of AMBERLITE(R) XAD-4 CAS#37380-42-0Ion exchange resin is a kind of functional polymer that can exchange with ions of the same sign in aqueous solution. It is essentially a cross-linked polymer acid or polymer base. Phenolic cation exchange resin was first introduced in 1935, and industrial production began in Germany in 1939 and the United States in 1941. After World War II, polystyrene and polyacrylic acid ion exchange resins were put into production one after another. After the 1960s, macroporous ion exchange resins were developed.
