Application:
Shanghai Ruifu Chemical Co., Ltd. is the leading manufacturer and supplier of 2-Bromopropene (CAS: 557-93-7) with high quality, widely used in organic synthesis, synthesis of pharmaceutical intermediates and active pharmaceutical ingredient (API) synthesis. 2-Bromopropene is used as a solvent and as an intermediate for organic synthesis. 2-Bromopropene (CAS: 557-93-7) is an intermediate of Carfilzomib (CAS: 868540-17-4) in the treatment of refractory multiple myeloma. In July 2012, the US FDA approved Carfilzomib for the treatment of patients with multiple myeloma (MM) who have received at least two prior therapies including bortezomib and an immunomodulatory agent and have demonstrated disease progression within 60 days of completion of the last therapy.
