Description

17α-Estra-1,3,5(10)-Triene-3,17-Diol-17-Heptanoate is a synthetic steroid ester, specifically a heptanoate derivative of estradiol. This compound is of significant interest in pharmaceutical research and development, particularly for its potential as a long-acting prodrug or as a key intermediate in the synthesis of more complex steroidal molecules. It is primarily utilized by research institutions, pharmaceutical manufacturers, and fine chemical suppliers engaged in the development of hormone therapies and advanced steroidal compounds.

Application

• Pharmaceutical Intermediate: Serves as a critical building block in the multi-step synthesis of novel steroidal active pharmaceutical ingredients (APIs).
• Research & Development: Used in academic and industrial laboratories for studying steroid metabolism, receptor binding, and prodrug delivery mechanisms.
• Hormone Prodrug Development: Investigated for its potential to provide sustained release of estradiol due to the lipophilic heptanoate ester moiety.
• Reference Standard: Employed as an analytical standard in quality control (QC) and research laboratories for method development and compound identification via HPLC, GC-MS, or NMR.
• Fine Chemical Synthesis: Acts as a specialized starting material for custom synthesis and contract manufacturing of high-value steroidal compounds.
