Description

C29 Ring-C Monoaromatic Sterane (5Beta(H),10Beta(Ch3)/5Alpha(H),10Alpha(Ch3)) is a high-purity, structurally defined sterane biomarker used as a critical reference standard and research chemical. This compound is essential for precise geochemical analysis, enabling the detailed characterization of organic matter maturity and depositional environments in petroleum systems. It is primarily utilized by research institutions, oil and gas laboratories, and specialty chemical manufacturers involved in advanced organic geochemistry and biomarker studies. The product is supplied with a CAS registry number of 205176-21-2.

Application

• Geochemical Biomarker Standard: Serves as a certified reference material for the calibration of analytical instruments (GC-MS, GC-MS/MS) in petroleum exploration and basin analysis.
• Organic Matter Maturity Assessment: Used to develop and validate maturity parameters (e.g., sterane isomerization ratios) for evaluating the thermal history of source rocks.
• Environmental Forensics: Acts as a specific tracer in oil spill identification and source correlation studies due to its diagnostic structural signature.
• Academic and Industrial Research: Fundamental for studies in organic geochemistry, sedimentary geology, and the development of new analytical methodologies for complex hydrocarbon mixtures.
• Petroleum Product Characterization: Aids in the detailed fingerprinting of crude oils and refined products to understand origin and alteration processes.

Quality Control

Every batch of our C29 Ring-C Monoaromatic Sterane is manufactured and analyzed under strict quality protocols to ensure identity, purity, and consistency. We employ advanced chromatographic and spectroscopic techniques, including GC-MS and NMR, for comprehensive characterization. A detailed Certificate of Analysis (COA) is provided with each shipment, documenting the purity, chromatographic profile, and structural confirmation. Our quality system is designed to meet the exacting requirements of research and analytical reference standards.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept sealed in a dry environment to prevent adsorption of water vapor. For long-term storage, consider using desiccant in the storage area.
