Fulvestrant is a selective estrogen receptor downregulator (SERD) used primarily as an anti-estrogen therapy in the treatment of hormone receptor-positive breast cancer. It binds to estrogen receptors, preventing estrogen from binding and promoting receptor degradation. This chemical is a white to off-white powder with the CAS number 129453-61-8, molecular formula C32H47F5O3S, and a molecular weight of 606.77 g/mol. Store at 2 to 8°C under controlled conditions. It carries a **Danger** signal word due to its hazardous properties. Molekula supplies Fulvestrant from research to bulk quantities with full documentation and ISO 9001:2015 traceability.
