Description

17Alpha(H),21Alpha(H)-22Rs-Bishomohopane is a high-purity, structurally defined pentacyclic triterpenoid compound, specifically a bishomohopane. This compound matters as a critical reference standard and biomarker in geochemical and environmental research, providing essential data for the analysis of petroleum, sediments, and ancient organic matter. It is primarily needed by analytical laboratories, research institutions, and energy sector companies engaged in organic geochemistry, petroleum exploration, and environmental forensics to calibrate instruments and interpret complex hydrocarbon mixtures.

Application

• Geochemical Biomarker Analysis: Serves as a key internal standard or reference compound for the identification and quantification of hopanoids in crude oils, rock extracts, and sediments.
• Petroleum Exploration & Source Rock Evaluation: Used to assess thermal maturity, depositional environments, and the origin of petroleum through biomarker fingerprinting studies.
• Environmental Forensics: Employed in tracing the source and fate of hydrocarbons in contaminated sites and for oil spill identification.
• Organic Geochemistry Research: A vital tool in academic and industrial research for understanding diagenetic and catagenetic pathways of organic matter.
• Analytical Method Development: Used to develop and validate sophisticated chromatographic (GC, GC-MS, LC-MS) methods for complex hydrocarbon analysis.
• Archaeological & Paleontological Studies: Acts as a biomarker in studying ancient ecosystems and biological precursors in fossils.
