Cabazitaxel Related Products
Cabazitaxel is a chemotherapy drug used primarily for treating metastatic castration-resistant prostate cancer. It is often used in patients who have previously been treated with docetaxel. Cabazitaxel works by inhibiting cell division through microtubule disruption. It is administered intravenously and can have side effects like neutropenia and diarrhea.
Cleanchem is a trusted provider of premium pharmaceutical reference materials, specializing in Cabazitaxel and its associated compounds. Our catalog includes pharmacopeial and non-pharmacopeial Cabazitaxel impurities, metabolites, nitrosamine derivatives (N-NO compounds), and stable isotope-labeled products. These reference standards play a critical role in pharmaceutical R&D, supporting activities such as product formulation, ANDA and DMF submissions, quality assurance, analytical method development, and stability assessments.
All Cabazitaxel-related substances undergo comprehensive characterization and are delivered with complete Certificates of Analysis and supporting analytical documentation to ensure regulatory adherence. Upon request, we can offer EP/USP traceable standards. Our products are routinely re-evaluated to maintain consistent quality and performance.
