Bendamustine

Bendamustine is a bifunctional alkylating agent with structural features of both nitrogen-mustard alkylators and purine-analogue antimetabolites, used for chronic lymphocytic leukaemia and indolent non-Hodgkin lymphoma. Simson Pharma's Bendamustine reference standard and impurities support the stringent stability-indicating testing this antineoplastic requires.

Simson Pharma Global Ltd. (UK) and Simson Pharma Global LLC (USA) supply high-quality Bendamustine Reference Standards, pharmacopoeial reference materials, and its related impurities to pharmaceutical manufacturers, CROs, analytical laboratories, universities, and regulatory organizations worldwide. To service the Europe and America market efficiently, Simson Pharma Limited has set up Simson Pharma Global Ltd. in United Kingdom and Simson Pharma Global LLC in USA respectively.
