CAS 19957-51-8

Tamoxifen Citrate EP Impurity C

Description:

Tamoxifen Citrate EP Impurity C, with the CAS number 19957-51-8, is a chemical compound associated with the pharmaceutical agent tamoxifen, which is primarily used in the treatment of breast cancer. This impurity is a byproduct that may arise during the synthesis of tamoxifen and is characterized by its specific molecular structure and properties. Typically, impurities like this can exhibit varying degrees of biological activity and stability compared to the parent compound. Tamoxifen itself functions as a selective estrogen receptor modulator (SERM), and impurities may influence the overall efficacy and safety profile of the drug. The identification and quantification of such impurities are crucial in pharmaceutical development and quality control to ensure the safety and effectiveness of the final product. Analytical techniques such as high-performance liquid chromatography (HPLC) and mass spectrometry are commonly employed to characterize and monitor impurities in pharmaceutical formulations. Understanding the characteristics of impurities like Tamoxifen Citrate EP Impurity C is essential for regulatory compliance and therapeutic efficacy.
