Description

4b,4'b,5,5',6,6',7,7',8,8',8a,8'a,9,9',10,10'-Hexadecahydro-2,2'-dihydroxy-4b,4'b,8,8'-tetramethyl-1,1'-bis(1-methylethyl)-3,3'-biphenanthrene-8,8'-dicarboxylic acid is a complex, high-purity diterpenoid dicarboxylic acid derivative. This compound is valued for its unique sterically hindered biphenanthrene core, which serves as a sophisticated chemical intermediate and research building block in advanced organic synthesis. It is primarily sought by R&D and process development teams in the pharmaceutical and fine chemical industries for the development of novel active compounds and specialty materials.

Application

• Pharmaceutical Intermediate: Key starting material or advanced intermediate in the synthesis of complex drug candidates, particularly those requiring rigid, polycyclic frameworks.
• Organic Synthesis Building Block: Utilized in research to construct complex natural product analogs or novel molecular architectures due to its intricate, multi-ring structure.
• Ligand and Catalyst Development: Potential precursor for creating sterically demanding ligands used in asymmetric catalysis and metal-organic frameworks (MOFs).
• Material Science Research: Investigated for the development of specialty polymers or organic electronic materials with specific conformational properties.
• Reference Standard: Serves as a high-purity analytical standard for quality control and method development in analytical laboratories.

Quality Control

Our production of this advanced intermediate adheres to strict quality management protocols. Every batch is characterized using advanced analytical techniques including HPLC, NMR, and MS to ensure structural identity and purity. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with each shipment to support your R&D and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed to exclude moisture. For long-term storage, consider using desiccants or an inert atmosphere.
