Description

17Beta(H),21Alpha(H)-(22R)-Tetrakishomohopane 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 molecular fossil, providing critical insights into the origin, maturity, and biodegradation of organic matter in petroleum systems. It is an essential analytical standard for laboratories in the oil & gas, environmental science, and advanced materials research sectors requiring precise biomarker identification and quantification.

Application

• Geochemical Biomarker Analysis: Serves as a critical reference standard for identifying and quantifying hopanoids in crude oils, source rocks, and sediments to assess thermal maturity and depositional environments.
• Petroleum Exploration & Characterization: Used in oil-oil and oil-source rock correlation studies to understand the origin, migration, and alteration history of petroleum reserves.
• Environmental Forensics: Employed as a tracer to identify sources of hydrocarbon contamination (e.g., oil spills) and to study the biodegradation processes in impacted ecosystems.
• Organic Geochemistry Research: Essential for academic and industrial research into the diagenetic and catagenetic pathways of biological precursors in the geological record.
• Analytical Method Development: Used to calibrate and validate advanced analytical techniques such as Gas Chromatography-Mass Spectrometry (GC-MS) and Liquid Chromatography-Mass Spectrometry (LC-MS).
• High-Purity Reference Material: Supplied to certified reference material (CRM) producers and testing laboratories for quality assurance and control programs.
