Exemestane Impurity 13, with the CAS number 152764-29-9, is a chemical compound that is recognized as an impurity associated with the aromatase inhibitor exemestane, which is used primarily in the treatment of hormone receptor-positive breast cancer. This impurity is characterized by its specific molecular structure, which may differ slightly from the parent compound, potentially affecting its pharmacological properties. Typically, impurities like Exemestane Impurity 13 are monitored during the synthesis and formulation of pharmaceuticals to ensure product safety and efficacy. The presence of such impurities can influence the stability, bioavailability, and overall therapeutic effectiveness of the drug. Analytical techniques such as high-performance liquid chromatography (HPLC) and mass spectrometry are commonly employed to identify and quantify impurities in pharmaceutical preparations. Understanding the characteristics of impurities is crucial for regulatory compliance and quality assurance in drug development and manufacturing processes.
