Description

Estra-1,3,5(10),7-Tetraene-3,17-Diol, 3-(Hydrogen Sulfate), Monosodium Salt, (17Alpha)- is a chemically modified steroid derivative, specifically a monosodium sulfate ester of a tetraene estradiol analog. This compound is valued for its role as a key synthetic intermediate in the development of novel pharmaceutical agents, particularly in hormone-related research and specialty therapeutics. It is primarily utilized by advanced pharmaceutical R&D laboratories, fine chemical manufacturers, and academic institutions engaged in steroid chemistry and drug discovery programs.

Application

• Pharmaceutical Intermediate: Critical building block for the synthesis of advanced steroid-based drug candidates and novel therapeutic molecules.
• Research & Development: Used in academic and industrial laboratories for studying structure-activity relationships (SAR) in steroid chemistry.
• Reference Standard: Serves as a high-purity analytical standard for method development and quality control in pharmaceutical analysis.
• Biochemical Research: Employed in studies investigating estrogen receptor interactions and metabolic pathways of modified steroids.
• Fine Chemical Synthesis: Intermediate for the production of more complex, target-specific steroid derivatives with potential biological activity.
