Description

(9β,10α,23E)-2β,16α,20,25-Tetrahydroxy-9-Methyl-19-Norlanosta-5,23-Diene-3,11-Dione is a highly functionalized norlanostane triterpenoid derivative, valued for its complex stereochemistry and bioactive potential. This compound serves as a critical advanced intermediate in pharmaceutical research and synthesis, particularly for developing novel therapeutic agents. It is primarily sought by research institutions and pharmaceutical R&D departments focused on steroid and natural product chemistry.

Application

• Pharmaceutical Intermediate: Key building block for the synthesis of novel steroid-based drugs and bioactive molecules.
• Biochemical Research: Used as a reference standard or probe in studies of enzyme inhibition and receptor binding related to triterpenoid pathways.
• Natural Product Synthesis: Serves as a sophisticated precursor in the total or semi-synthesis of complex natural products with lanostane skeletons.
• Academic Research: Employed in university and institutional labs for methodological development in organic and medicinal chemistry.
• Process Development: Utilized in scaling up synthetic routes for potential active pharmaceutical ingredients (APIs).

Quality Control

Our high-purity triterpenoid intermediates are manufactured under strict quality systems. Each batch is characterized and tested to ensure identity, purity, and consistency, supported by comprehensive analytical data including HPLC, NMR, and MS. A detailed Certificate of Analysis (COA) is provided with every shipment, and custom purity grades are available to meet specific research or cGMP starting material requirements.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) at a controlled room temperature (15-25°C) to prevent oxidation and degradation. The container should be kept in a cool, dry, and well-ventilated place away from incompatible materials.
