Description

17Beta(H), 21Alpha(H)-Hopane is a specific, high-purity pentacyclic triterpane compound, also known as 17β(H),21α(H)-Hopane, which serves as a critical biomarker and reference standard in geochemical and environmental analysis. Its well-defined stereochemistry makes it an essential tool for precise identification and quantification in complex organic matrices. This compound is primarily required by research laboratories, environmental testing facilities, and petroleum geochemistry companies engaged in source rock evaluation, oil-oil correlation, and pollution fingerprinting studies.

Application

• Geochemical Biomarker Analysis: Used as a key internal or external standard for gas chromatography-mass spectrometry (GC-MS) to identify and quantify hopanoids in crude oils, source rocks, and sediments.
• Petroleum Exploration & Correlation: Essential for maturity assessments and determining the origin of petroleum fluids through biomarker fingerprinting.
• Environmental Forensics: Acts as a diagnostic tracer for identifying sources of hydrocarbon contamination (e.g., oil spills) in soil and water.
• Organic Geochemistry Research: A fundamental standard in academic and industrial research studying the diagenesis and catagenesis of organic matter.
• Method Development & Validation: Serves as a certified reference material (CRM) for developing and validating analytical methods in chromatography.
• Archaeological & Paleoenvironmental Studies: Used as a biomarker to study past environments and biological activity in geological records.
