Description

18Alpha(H)-22,29,30-Trisnorneohopane is a high-purity, triterpenoid biomarker compound belonging to the hopane series. It serves as a critical reference standard and research chemical for geochemical and environmental analysis, particularly in petroleum exploration and pollution studies. This compound is essential for researchers and analytical laboratories in the oil & gas, environmental science, and academic research sectors who require precise biomarkers for source rock identification, maturity assessments, and biodegradation studies.

Application

• Geochemical Biomarker Analysis: Used as a key internal or external standard in gas chromatography-mass spectrometry (GC-MS) for identifying and quantifying hopanoids in crude oils, source rocks, and sediments.
• Petroleum Exploration & Source Rock Evaluation: Critical for assessing the origin, thermal maturity, and depositional environment of petroleum source rocks through biomarker fingerprinting.
• Environmental Forensics & Pollution Monitoring: Employed to trace the source and extent of hydrocarbon contamination (e.g., oil spills) in soil and water by analyzing hopane distributions.
• Organic Geochemistry Research: A fundamental tool in academic and industrial research to study diagenesis, catagenesis, and the biogeochemical cycling of organic matter.
• Method Development & Validation: Serves as a certified reference material (CRM) for developing, calibrating, and validating analytical methods in chromatography.
• Biodegradation Studies: Used to monitor the microbial degradation of complex hydrocarbon mixtures, as hopanes are highly resistant to biodegradation.
