Description

Phenanthrene, 1,2,3,4,4A,9,10,10A-Octahydro-1,1,4A-Trimethyl-, (4As,10As)- is a high-purity, stereochemically defined octahydrophenanthrene derivative. This compound serves as a valuable advanced synthetic intermediate and a crucial building block in organic synthesis, particularly for constructing complex polycyclic frameworks. It is primarily sought by R&D laboratories and chemical manufacturers in the pharmaceutical, agrochemical, and specialty chemical sectors for developing novel active ingredients and functional materials.

Application

• Pharmaceutical Intermediate: A key chiral precursor in the synthesis of steroidal compounds, triterpenoids, and other biologically active molecules with complex polycyclic structures.
• Agrochemical Research: Used in the development of novel pesticides and herbicides, leveraging its rigid, functionalizable hydrocarbon skeleton.
• Material Science: Serves as a building block for organic semiconductors, liquid crystals, and other advanced organic materials requiring specific stereochemistry and planarity.
• Organic Synthesis: An important starting material for Diels-Alder reactions, hydrogenation studies, and the construction of perhydrophenanthrene systems in academic and industrial research.
• Fragrance & Flavor Chemistry: Potential use as an intermediate for synthesizing specific musky or amber-type odorants due to its polycyclic nature.
• Reference Standard: Supplied as a high-purity analytical standard for chromatography and spectroscopy in quality control and method development laboratories.
