Description

Trimethyl-[(13S,17S)-13-methyl-3-[2-(1-methyl-2,3,4,5-tetrahydropyrrol-1-yl)ethoxy]-6,7,8,9,11,12,14,15,16,17-decahydrocyclopenta[a]phenanthren-17-yl]azanium diiodide is a high-purity, complex steroidal ammonium salt diiodide derivative designed for advanced research and pharmaceutical development. This compound is valued for its specific stereochemistry and functional groups, making it a critical intermediate or reference standard in synthetic organic chemistry. It is primarily sought by pharmaceutical R&D teams, contract research organizations (CROs), and academic institutions focused on medicinal chemistry and steroid-based drug discovery.

Application

• Pharmaceutical Intermediate: A key building block in the multi-step synthesis of novel steroidal drug candidates targeting hormone receptors.
• Medicinal Chemistry Research: Used as a precise chemical tool for structure-activity relationship (SAR) studies to optimize biological activity and selectivity.
• Reference Standard: Serves as a high-purity analytical standard for method development, validation, and quality control in HPLC and LC-MS analysis.
• Biochemical Probe: Potential use in investigating steroidal pathways and interactions at a molecular level in biological systems.
• Academic Synthesis: Employed in advanced educational and research settings to demonstrate complex organic synthesis techniques.
• Process Development: Supports scale-up and optimization studies for the production of specialized active pharmaceutical ingredients (APIs).
