One other major classes of polar-embedded groups are ureas and carbamates. They are really received by reacting isocyanates with Major amines and alcohols respectively. These purposeful teams give more polar interactions as hydrogen bond acceptors and fewer ionic interactions when compared to alkyl phases, leading to selectivity discrepancies for polarizable compounds when strengthening peak form of primary analytes (18).
