Description

21,23-Epoxy-3β,23-Dihydroxy-9,19-Cyclo-5α-Lanost-24-En-26-Oic Acid 26,23-Lactone is a highly functionalized lanostane-type triterpenoid derivative, valued for its complex and rigid molecular architecture. This compound serves as a critical advanced intermediate and reference standard in the research and development of novel bioactive molecules. It is primarily sought by pharmaceutical R&D teams, academic research institutions, and fine chemical manufacturers focused on steroid and natural product chemistry.

Application

• Pharmaceutical Intermediate: A key synthetic precursor for the development of novel steroidal drugs and therapeutic agents.
• Biochemical Research: Used as a reference standard and probe in studies of enzyme inhibition, receptor binding, and metabolic pathways.
• Natural Product Synthesis: Serves as a complex starting material or intermediate in the total synthesis of bioactive natural products.
• Academic & Discovery Chemistry: Employed in medicinal chemistry programs for structure-activity relationship (SAR) studies and lead optimization.
• Analytical Standard: Provides a high-purity benchmark for analytical method development and validation (e.g., HPLC, LC-MS) in quality control laboratories.
