Description

C27 Ring-C Monoaromatic Sterane (5Beta(H),10Beta(Ch3)/5A(H),10Beta(Ch3)) CAS NO 98819-91-1 is a high-purity, structurally defined monoaromatic sterane biomarker used as a critical reference standard and research chemical. This compound is essential for precise geochemical analysis, enabling the accurate identification and quantification of organic matter maturity and depositional environments in petroleum systems. It is primarily required by research laboratories, oil and gas companies, and environmental testing facilities engaged in advanced organic geochemistry, petroleum exploration, and biomarker studies.

Application

• Geochemical Biomarker Analysis: Serves as a key reference standard for identifying and quantifying monoaromatic steroids in crude oils and source rock extracts.
• Petroleum Exploration & Source Rock Evaluation: Used to assess thermal maturity and the depositional environment (e.g., salinity, redox conditions) of source rocks.
• Oil-Oil & Oil-Source Rock Correlation: Aids in establishing genetic relationships between different petroleum samples and their potential source rocks.
• Environmental Forensics: Employed as a diagnostic tracer to identify the source and weathering processes of petroleum hydrocarbons in contaminated sites.
• Organic Geochemistry Research: Fundamental for academic and industrial research into the diagenesis and catagenesis of steroidal hydrocarbons.
• Analytical Method Development & Calibration: Used to develop and validate high-precision analytical methods such as GC-MS and GC-MS/MS for biomarker analysis.
• Reference Material Production: Sourced by manufacturers of certified reference materials (CRMs) for the petrochemical industry.
