Description

(1R,4As,7E,9R,11Ar)-4-[(1R,2R)-1,2-Diacetoxy-4-Methyl-3-Pentenyl]-1,4A,5,6,9,10,11,11A-Octahydro-7-Methyl-11-Methylenecyclonona[C]Pyran-1,9-Diol Diacetate is a high-purity, complex diterpenoid derivative with significant potential as a key synthetic intermediate. This compound matters for its precise stereochemistry and functional groups, which are critical for constructing advanced molecular architectures in pharmaceutical research. It is primarily needed by R&D chemists and process development scientists in the pharmaceutical, agrochemical, and fine chemical industries for the synthesis of novel bioactive compounds.

Application

• Pharmaceutical Intermediate: Serves as a sophisticated building block for the synthesis of novel drug candidates, particularly in oncology and anti-inflammatory research.
• Chemical Biology Probe: Used in medicinal chemistry to study structure-activity relationships (SAR) and biological pathways due to its complex, natural product-like scaffold.
• Asymmetric Synthesis: Acts as a chiral template or starting material for the preparation of enantiomerically pure compounds in advanced organic synthesis.
• Agrochemical Research: Investigated as a precursor for developing new plant growth regulators or pesticides with novel modes of action.
• Academic & Institutional R&D: Employed in university and government laboratories for fundamental research in synthetic methodology and natural product chemistry.

Quality Control

Our (1R,4As,7E,9R,11Ar)-4-[(1R,2R)-1,2-Diacetoxy-4-Methyl-3-Pentenyl]-1,4A,5,6,9,10,11,11A-Octahydro-7-Methyl-11-Methylenecyclonona[C]Pyran-1,9-Diol Diacetate is produced under strict quality management systems. Each batch undergoes comprehensive analytical characterization including HPLC, NMR, and MS to confirm identity, purity, and stereochemical integrity. Certificates of Analysis (COA) with detailed chromatographic and spectroscopic data are available upon request to support your regulatory and R&D documentation.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). This compound is hygroscopic (moisture-sensitive); therefore, containers must be kept tightly sealed and consideration should be given to storage under an inert atmosphere for long-term preservation of quality.
