Description

Diethylstilbestrolmonomethylether is a synthetic, non-steroidal estrogen derivative, specifically the monomethyl ether of diethylstilbestrol. This compound is valued for its potent estrogenic activity and serves as a critical intermediate in pharmaceutical research and synthesis. It is primarily required by research institutions and pharmaceutical manufacturers developing or producing hormone-related therapies and reference standards.

Application

• Pharmaceutical Intermediate: A key building block in the synthesis of steroidal and non-steroidal hormonal agents.
• Biochemical Research: Used as a reference standard and active agent in studies of estrogen receptor binding and hormonal pathways.
• Veterinary Medicine: Employed in research for developing treatments related to reproductive health in animals.
• Academic Research: Serves as a model compound in organic chemistry and medicinal chemistry for studying structure-activity relationships of estrogenic compounds.
• Analytical Standard: Utilized in quality control laboratories for method development and calibration in HPLC, GC, or other analytical techniques.
