Description

trans-Diethyl Stilbestrol Acetate is a synthetic, non-steroidal estrogen derivative. This compound is valued for its potent estrogenic activity and serves as a key intermediate in pharmaceutical research and development. It is primarily utilized by research institutions and pharmaceutical companies involved in endocrinology, oncology, and the synthesis of hormone-related compounds.

Application

• Pharmaceutical Intermediate: A critical building block in the synthesis of steroidal and non-steroidal hormonal agents.
• Biochemical Research: Used as a reference standard and active compound in studies of estrogen receptor (ER) binding and signaling pathways.
• Veterinary Medicine: Historically employed in growth promotion and therapeutic applications in livestock, subject to regional regulatory approvals.
• Academic Research: Serves as a model compound in medicinal chemistry for structure-activity relationship (SAR) studies of estrogen analogs.
• Reference Standard: Utilized in analytical laboratories for method development and quality control testing via HPLC, GC, or spectroscopy.
