Common ESI adducts are important in mass spectrometry for identifying and analyzing compounds. These adducts form when ions interact with solvent molecules, leading to various species like [M+H]+ (protonation), [M+Na]+ (sodium adduction), and [M-H]- (deprotonation). Understanding these adducts is crucial for accurate chemical characterization.
