Amoxicillin EP Impurity G (Crude) is a degradation byproduct formed via oxidative cleavage of the side-chain amino group in Amoxicillin, resulting in a substituted thiazole moiety conjugated to a ฮฒ-lactam core with an additional hydroxylated aromatic substituent. This impurity retains the core ฮฒ-lactam structure but features a modified side chain containing a carboxylic acid derivative and an oxidized sulfur center. It serves as a critical HPLC reference standard for quantifying this specific degradation product in Amoxicillin drug substance purity profiling.
