Description

N-Nitrosodiethanolamine (NDIEA), CAS 1116-54-7, is a low-molecular-weight nitrosamine impurity of molecular formula C4H10N2O3 and molecular weight 134.13 g/mol. This compound is structurally consistent with nitrosative conversion of diethanolamine under conditions involving nitrite, acidic media, or process contamination. As a member of the N-nitrosamine class, it is treated as a potentially genotoxic impurity within modern regulatory frameworks, including ICH M7 risk assessment. Quantification typically requires highly selective LC-MS/MS or GC-MS methods, often with isotopically labeled internal standards, because trace-level determination is challenged by volatility, matrix effects, and background contamination.
