Description

17Beta(H), 21Beta(H)-Hopane is a pentacyclic triterpane, a specific stereoisomer of the hopane family that serves as a crucial biomarker and reference standard in geochemical and environmental analysis. Its stable molecular structure makes it an invaluable internal standard for quantifying complex hydrocarbon mixtures and studying organic matter diagenesis. This high-purity compound is essential for researchers and analytical laboratories in the petroleum geochemistry, environmental forensics, and organic geochemistry sectors.

Application

• Geochemical Biomarker Studies: Used as a key internal standard for the quantification of hopanoids and other terpanes in crude oils, source rocks, and sediments to assess thermal maturity and organic matter origin.
• Petroleum Exploration & Characterization: Critical for fingerprinting oils, correlating oils to their source rocks, and understanding depositional environments in upstream oil and gas research.
• Environmental Forensics: Employed in tracing the source and weathering of petroleum hydrocarbon contaminants in soil and water samples following spills or leaks.
• Archaeological & Geological Dating: Acts as a stable reference compound in studies investigating the age and degradation pathways of organic materials over geological timescales.
• Analytical Method Development & Validation: Serves as a high-purity calibration standard for Gas Chromatography-Mass Spectrometry (GC-MS) and other chromatographic techniques in laboratory settings.
• Organic Geochemistry Research: Fundamental for academic and industrial research into the transformation of biological precursors into geological hydrocarbons.
