Description

D-Homoestradiol is a synthetic steroid derivative of estradiol, characterized by the expansion of the D-ring in its molecular structure. This compound is a critical intermediate in advanced pharmaceutical research and development, particularly for the synthesis of novel therapeutic agents. It is primarily utilized by research institutions and pharmaceutical companies engaged in the development of hormone-related therapies and for use as a reference standard in analytical chemistry.

Application

• Pharmaceutical Intermediate: A key building block in the synthesis of specialized steroidal drugs and novel hormonal compounds.
• Research & Development: Used as a reference standard and a starting material in medicinal chemistry for studying structure-activity relationships (SAR).
• Biochemical Research: Employed in laboratory studies to investigate estrogen receptor interactions and metabolic pathways.
• Analytical Standard: Serves as a high-purity certified reference material (CRM) for quality control and method validation in HPLC and GC analysis.
