Description

17Alpha(H),21Beta(H)-22Rs-Trishomohopane is a high-purity, triterpenoid biomarker compound belonging to the hopane series. This compound is of significant value in geochemical and environmental research for its role as a stable molecular fossil. It is primarily required by analytical laboratories, research institutions, and energy sector companies engaged in petroleum geochemistry, source rock analysis, and environmental forensics to study organic matter maturity, migration, and biodegradation.

Application

• Geochemical Biomarker Analysis: Used as a key internal standard or reference compound in gas chromatography-mass spectrometry (GC-MS) for the quantification of hopanoids in crude oils, source rocks, and sediments.
• Petroleum Exploration & Source Rock Evaluation: Critical for assessing thermal maturity, depositional environments, and the origin of petroleum through biomarker fingerprinting studies.
• Environmental Forensics: Employed in tracing the source and extent of hydrocarbon contamination (e.g., oil spills) and monitoring biodegradation processes in soil and water.
• Organic Geochemistry Research: Serves as a fundamental research standard in academic and industrial laboratories for studying diagenesis and catagenesis of organic matter.
• Calibration Standard: Used to calibrate analytical instruments and validate methods for the accurate identification and measurement of complex hopane distributions.
