Description

(17α,21β)-Hopane is a pentacyclic triterpenoid compound belonging to the hopane class, recognized as a significant biomarker in geochemistry and environmental studies. Its stable molecular structure makes it an invaluable internal standard and reference material for analytical quantification in complex organic matrices. This high-purity standard is essential for researchers and quality control laboratories in the petroleum, environmental science, and geochemical research sectors who require reliable and traceable compounds for precise analysis.

Application

• Geochemical Biomarker Analysis: Used as a key reference standard for identifying and quantifying hopanoids in crude oils, sediments, and rocks to assess thermal maturity and organic matter origin.
• Environmental Forensics: Serves as an internal standard in GC-MS analysis for tracing petroleum contamination and studying the biodegradation of hydrocarbons in soil and water.
• Petroleum Geochemistry Research: Critical for calibrating instruments and validating methods in the study of molecular fossils to understand depositional environments and hydrocarbon generation.
• Phytochemical Reference Standard: Acts as a purity standard in the isolation and study of triterpenoids from natural plant sources.
• Quality Control in Analytical Laboratories: Employed as a certified reference material (CRM) to ensure accuracy and precision in chromatographic assays for complex organic mixtures.
