Description

Gammacerane CAS NO 559-65-9 is a pentacyclic triterpane biomarker of significant interest in organic geochemistry and petroleum exploration. Its presence and distribution serve as a powerful diagnostic tool for assessing the depositional environment and thermal maturity of crude oils and source rocks. This compound is essential for researchers and geochemists in the petroleum industry, environmental forensics, and academic institutions focused on paleoenvironmental reconstruction and oil-source correlation studies.

Application

• Biomarker Analysis in Petroleum Geochemistry: Used as a specific indicator for lacustrine (lake-derived) organic matter and high-salinity depositional environments in crude oils and source rock extracts.
• Oil-Source and Oil-Oil Correlation: Aids in fingerprinting petroleum fluids to determine genetic relationships and trace hydrocarbons back to their source rocks.
• Maturity Assessment: The ratio of gammacerane to other hopanoids (e.g., C30 hopane) is used as a parameter to evaluate the thermal maturity of petroleum.
• Paleoenvironmental Reconstruction: Applied in geological studies to interpret ancient water column stratification, salinity, and redox conditions in sedimentary basins.
• Environmental Forensics: Helps in identifying the source and fate of hydrocarbon contaminants in soil and water by providing a distinctive chemical signature.
• Reference Standard for Chromatography: Serves as a high-purity calibration standard for Gas Chromatography-Mass Spectrometry (GC-MS) analysis in research and commercial laboratories.
