Abstract
For the identification of the seven Nitrosamine Impurities i.e. N-Methyl-N-Nitrosopropane-1,3-diamine (Nitroso MAPA), N-Nitrosomethyl phenylamine (NMPA), N-Nitrosoethylisopropylamine (NEIPA), N-Nitroso-N-Methyl-4-Aminobutyric acid (NMBA), N-Nitrosodimethylamine (NDMA), N-Nitrosodiethylamine (NDEA), N-Nitrosodiisopropylamine (NDIPA) content in Cinacalcet Hydrochloride a sensitive, fast, linear, precise, and efficient liquid chromatography mass spectrometry method has been developed and validated. As a calcimimetics, cinacalcet hydrochloride is an active pharmaceutical ingredient that lowers blood calcium levels by telling the body to create less parathyroid hormone. It is known that amines react with nitrosating substances like nitrite to create nitrosamines. Residual amines in the APIs are the primary source of amines in the case of minor alkylnitrosamines like NDMA and NDEA. Although the degree of the risk of nitrosamine contamination has rarely been documented, residual amines in the APIs provide a possible problem. A simultaneous analytical method for amines that correspond to seven common small alkyl nitrosamines was developed and validated in this study. For every Nitrosamine Impurity, including N-Nitrosodimethylamine (NDMA), N-Nitroso-N-Methyl-4-Aminobutyric acid (NMBA), N-Nitrosodiethylamine (NDEA), N-Nitrosoethylisopropylamine (NEIPA), N-Nitrosodiisopropylamine (NDIPA), N-Nitrosomethylphenylamine (NMPA), and N-Methyl-N-Nitrosopropane-1,3-diamine (Nitroso MAPA), good linearity was obtained in the range of 0.009 ppm to 0.0450 ppm. The detection and quantification limits were 0.009 ppm. The range of recovery rates was 70% - 130%. With % RSD < 15%, repeatability was likewise good. Despite this, each nitrosamine impurity has a correlation of 0.990. Seven nitrosamine impurities in Cinacalcet Hydrochloride APIs will be identified using the proposed analytical LC-MS/MS method.
