Applications of Brush-Type Chiral Stationary Phases in New Chromatographic Techniques
… has been used to study the enantioseparations of hydantoins and thiohydantoins. Thiohydantoins are a class of compounds that typically result from the Edman degradation of peptides. The Edman degradation provides information about the primary structure of peptides, but it does not give any …
