Description

3-((3S,8R,9S,10R,13S,14S)-3-Acetoxy-10,13-Dimethyl-2,3,4,7,8,9,10,11,12,13,14,15-Dodecahydro-1H-Cyclopenta[A]Phenanthren-17-Yl)Pyridine 1-Oxide is a high-purity, steroidal pyridine N-oxide derivative of significant interest in advanced pharmaceutical research and development. This compound serves as a critical synthetic intermediate or a potential active pharmaceutical ingredient (API) precursor for creating novel therapeutic agents. It is primarily utilized by pharmaceutical R&D laboratories, contract research organizations (CROs), and fine chemical manufacturers focused on steroid-based drug discovery.

Application

• Pharmaceutical Intermediate: Key building block for the synthesis of novel steroid-based drug candidates targeting hormone receptors.
• Medicinal Chemistry Research: Used in structure-activity relationship (SAR) studies to develop new anti-inflammatory, anticancer, or neuroactive compounds.
• Reference Standard: Serves as a high-purity analytical standard for method development and quality control in API manufacturing.
• Biochemical Probe: Utilized in biochemical assays to study steroid metabolism and enzyme interactions due to its modified pyridine N-oxide moiety.
• Process Chemistry Development: Employed in scaling up synthetic routes for pilot and commercial-scale production of advanced pharmaceutical intermediates.
