Description

17Alpha(H),21Beta(H)-22Rs-Tetrakishomohopane is a high-purity, well-defined pentacyclic triterpenoid biomarker of significant interest in geochemical and environmental research. Its value lies in its role as a specific molecular indicator for assessing thermal maturity, depositional environments, and the origin of organic matter in petroleum systems and sediments. This compound is essential for researchers and analytical laboratories in the fields of petroleum geochemistry, environmental forensics, and advanced organic geochemical studies.

Application

• Biomarker Analysis in Petroleum Geochemistry: Used as a key diagnostic tool for evaluating the thermal maturity and depositional history of crude oils and source rocks.
• Environmental Forensics and Source Identification: Acts as a molecular fingerprint to trace the origin and fate of petroleum hydrocarbons in contaminated soils and sediments.
• Organic Geochemistry Research: Serves as a critical standard and reference compound in academic and industrial research for studying diagenetic and catagenetic pathways.
• Calibration Standard for Analytical Instrumentation: Used in Gas Chromatography-Mass Spectrometry (GC-MS) and Liquid Chromatography-Mass Spectrometry (LC-MS) for method development and quantitative analysis.
• Paleoenvironmental Reconstruction: Applied in studies to understand ancient climatic conditions and biological inputs based on sediment core analysis.
