Description

(2S)-2β-Ethenyl-2,3,4,4Aβ,4B,5,6,7,8,8Aβ,9,10-Dodecahydro-2,4Bα,8,8-Tetramethyl-3α,10Aα(1H)-Phenanthrenediol 3-Acetate is a high-purity, semi-synthetic diterpenoid derivative with a complex, functionalized phenanthrene core structure. This compound matters as a versatile and valuable chemical intermediate for advanced organic synthesis, particularly in the development of novel pharmacologically active molecules. It is primarily needed by pharmaceutical R&D laboratories and fine chemical manufacturers engaged in the synthesis of steroids, terpenoids, and other complex natural product analogs.

Application

• Pharmaceutical Intermediate: A key chiral building block for the research and development of new therapeutic agents, particularly in steroid and terpenoid-based drug discovery.
• Organic Synthesis Research: Used in academic and industrial laboratories to study complex cyclization, functionalization, and stereoselective transformation reactions.
• Reference Standard: Serves as a high-purity analytical standard for quality control and method development in analytical chemistry.
• Fine Chemical Production: An intermediate in the multi-step synthesis of specialty chemicals, flavors, and fragrances with complex molecular architectures.
• Biochemical Probe Development: Potential use in creating molecular probes to study biological pathways involving sterol or terpene receptors.
