Description

2A,17A(H),21A(H)-2-Methylhopane is a high-purity, structurally defined hopanoid compound, a class of pentacyclic triterpenoids with significant geochemical and biochemical relevance. This specific methylated hopane serves as a critical reference standard and biomarker for research and analytical applications, enabling precise identification and quantification in complex matrices. It is primarily utilized by research institutions, petrochemical laboratories, and environmental testing facilities engaged in organic geochemistry, petroleum exploration, and studies of microbial and plant-derived organic matter.

Application

• Biomarker and Geochemical Research: Acts as a key internal or external standard for gas chromatography-mass spectrometry (GC-MS) analysis of sedimentary rocks and crude oils to assess thermal maturity and organic matter origin.
• Petroleum Exploration & Source Rock Analysis: Used in fingerprinting studies to correlate oils with their source rocks and to understand depositional environments.
• Environmental Forensics: Employed as a tracer to identify the source and fate of petroleum hydrocarbons in contaminated soil and water samples.
• Microbial Biochemistry Studies: Useful in research on hopanoid-producing bacteria, investigating membrane composition and stability.
• Method Development & Validation: Serves as a high-purity calibrant for developing and validating analytical methods in specialized laboratories.
• Paleoenvironmental Reconstruction: Aids in reconstructing past ecological and climatic conditions based on the hopanoid signatures preserved in geological records.
