Study of the isomeric Maillard degradants, glycosylamine and Amadori rearrangement products, and their differentiation via MS

fingerprinting from collision‐induced decomposition of protonated ions
The focus of this work was to study glycosylamine and Amadori rearrangement products (ARPs), the two major degradants in the Maillard reactions of pharmaceutical interest, and utilize their MS2 fingerprints by liquid chromatography/high‐resolution tandem mass spectrometry (LC/HRMS2) to quickly distinguish the two isomeric degradants. These two types of degradants are frequently encountered in the compatibility
