Description

[20ξ,(+)]-3β,20-Dihydroxy-25-Methoxylanosta-7,9(11)-Diene-18-Oic Acid γ-Lactone CAS NO 24041-66-5 is a highly specific, oxidized lanostane-type triterpenoid derivative. This compound is valued for its complex, functionalized steroidal-like structure, which serves as a critical advanced intermediate or reference standard in pharmaceutical and biochemical research. It is primarily sought by R&D laboratories and fine chemical manufacturers engaged in the synthesis of novel bioactive molecules, particularly in oncology and metabolic disease studies.

Application

• Pharmaceutical Intermediate: A key chiral building block for the synthesis of novel steroid-based drug candidates targeting specific biological pathways.
• Biochemical Research: Used as a reference standard or probe in enzymatic studies and receptor binding assays due to its unique lanostane scaffold.
• Natural Product Synthesis: Serves as a sophisticated starting material or intermediate in the semi-synthesis of complex natural products and their analogs.
• Academic Research: Employed in universities and research institutes for studying structure-activity relationships (SAR) of triterpenoids.
• Process Development: Used in scaling up synthetic routes for potential Active Pharmaceutical Ingredients (APIs) in pre-clinical and clinical development stages.
