Description

17Beta(H),21Alpha(H)-25,28,30-Trisnorhopane is a high-purity, well-defined hopanoid compound, a class of pentacyclic triterpenoids valued as molecular biomarkers in geochemical and environmental studies. Its precise stereochemistry makes it an essential reference standard for analytical calibration and research. This compound is critical for laboratories and industries involved in petroleum geochemistry, environmental forensics, and organic geochemistry, where accurate identification and quantification of biological markers are required.

Application

• Geochemical Biomarker Standard: Serves as a critical internal or external standard for gas chromatography-mass spectrometry (GC-MS) analysis of crude oils, source rocks, and sediments.
• Petroleum Exploration & Characterization: Used to assess thermal maturity, depositional environments, and for oil-source rock correlation studies.
• Environmental Forensics: Aids in identifying sources of hydrocarbon contamination (e.g., oil spills) and understanding biodegradation processes.
• Organic Geochemistry Research: Fundamental for academic and industrial research into the diagenesis and catagenesis of organic matter.
• Reference Material for Calibration: Provides a known concentration and structure for calibrating analytical instruments and validating methods.
• Quality Control in Analytical Laboratories: Ensures accuracy and precision in the analysis of complex hydrocarbon mixtures.
