Description

5α-Lanosta-7,9(11),20(22)-Triene-3β,18-Diol Diacetate is a specific, high-purity lanostane-type triterpenoid derivative. This compound serves as a critical advanced intermediate or reference standard in pharmaceutical research and development, particularly for studying sterol biosynthesis and related biological pathways. It is essential for R&D laboratories and manufacturers in the pharmaceutical, biotechnology, and fine chemical sectors requiring well-characterized building blocks for synthetic chemistry or analytical method development.

Application

• Pharmaceutical Intermediate: A key synthetic precursor in the research and development of novel therapeutic agents, particularly those targeting cholesterol metabolism or with sterol-based activity.
• Biochemical Research: Used as a reference standard or probe in studies of enzyme inhibition, metabolic pathways, and sterol biosynthesis mechanisms.
• Reference Material: Serves as a high-purity certified reference material (CRM) for quality control and analytical method validation in pharmaceutical analysis.
• Fine Chemical Synthesis: Employed as a specialized building block for the synthesis of complex natural product analogs and other high-value chemical entities.
• Academic Research: Utilized in university and institutional labs for fundamental research in organic chemistry, medicinal chemistry, and chemical biology.
