Description

C27/C28 Triaromatic Steranes CAS NO 80382-32-7 are a class of specific aromatic steroid hydrocarbons, recognized as important molecular markers in geochemical and environmental studies. Their unique structure and stability make them invaluable for fingerprinting petroleum sources and understanding organic matter diagenesis. These compounds are essential for research and analytical laboratories in the petroleum, environmental science, and geochemistry sectors.

Application

• Biomarker Analysis in Petroleum Geochemistry: Used as specific tracers for assessing the maturity, source, and depositional environment of crude oils and source rocks.
• Environmental Forensics and Oil Spill Identification: Employed to correlate spilled oils with their suspected sources due to their resistance to biodegradation.
• Organic Geochemistry Research: Serves as a critical standard or reference material in academic and industrial research on sedimentary organic matter.
• Refinery Process Monitoring: Can be used to track the fate of specific biomarkers through refining processes.
• Calibration Standards for GC-MS: High-purity grades are used as calibration standards in gas chromatography-mass spectrometry (GC-MS) analysis.
