N-Nitroso- Prazosin EP Impurity D

N-Nitroso- Prazosin EP Impurity D is a chemical compound that is commonly used in pharmaceutical research and development. It is categorized as a nitroso compound, which means it contains a nitroso functional group (-NO) that is attached to a nitrogen atom. This impurity is formed during the synthesis of Prazosin, which is a medication used to treat hypertension and benign prostatic hyperplasia. The chemical formula of N-Nitroso- Prazosin EP Impurity D is C19H22N6O3, and its molecular weight is 382.42 g/mol. It is a pale yellow crystalline powder that is sparingly soluble in water and organic solvents. In terms of its usage, N-Nitroso- Prazosin EP Impurity D is used as a reference standard for the identification and quantification of Prazosin impurities in pharmaceutical formulations. It is also used as a starting material in the synthesis of other nitroso compounds. It is important to note that nitroso compounds have been found to have potential carcinogenic effects, and therefore, their use in pharmaceuticals is strictly regulated. The International Conference on Harmonization (ICH) guidelines recommend that the levels of N-Nitroso- Prazosin EP Impurity D in pharmaceutical formulations should not exceed 0.1%. Additionally, strict quality control measures are put in place to ensure that the levels of impurities in pharmaceutical products are within acceptable limits.
