Description

17Alpha(H), 21Beta(H)-25,30-Bisnorhopane is a high-purity, structurally defined pentacyclic triterpenoid biomarker. This compound is of significant value in geochemical and environmental research for its role as a diagnostic tracer in petroleum exploration and pollution source identification. It is primarily utilized by analytical laboratories, research institutions, and energy sector companies involved in advanced hydrocarbon analysis and biomarker studies.

Application

• Geochemical Biomarker Analysis: Used as a reference standard for identifying and quantifying hopanoid derivatives in crude oils, source rocks, and sediments to assess thermal maturity and depositional environments.
• Petroleum Exploration & Reservoir Characterization: Serves as a critical internal standard or calibration compound in GC-MS workflows to correlate oils with their source rocks and understand migration pathways.
• Environmental Forensics: Employed in tracing the origin and weathering of petroleum hydrocarbons in contaminated soils, groundwater, and marine ecosystems following spills.
• Organic Geochemistry Research: Essential for academic and industrial research into the diagenetic and catagenetic pathways of biological precursors in the geological record.
• Method Development & Validation: Used by analytical instrument manufacturers and testing laboratories to develop and validate chromatographic and mass spectrometric methods for complex hydrocarbon mixtures.
• Quality Control for Reference Material Producers: Acts as a high-purity starting material or comparator for companies synthesizing and certifying complex geochemical standard mixtures.
