Description

2,4-Dimethyldibenzothiophene is a high-purity, polycyclic aromatic sulfur heterocycle (PASH) compound, identified by CAS NO 31317-18-7. This compound serves as a critical reference standard and analytical marker for the identification and quantification of complex sulfur-containing organic mixtures. It is essential for researchers and quality control laboratories in the petrochemical, environmental analysis, and advanced materials research sectors who require precise molecular standards for calibration and method development.

Application

• Petroleum Geochemistry & Fuel Analysis: Used as a diagnostic marker and internal standard in GC-MS for source rock typing, oil-oil correlation, and assessing the thermal maturity of crude oils.
• Environmental Monitoring: Acts as a reference compound for analyzing polycyclic aromatic sulfur heterocycles (PASHs) in soil, sediment, and water samples to track pollution sources.
• Catalysis & Hydrodesulfurization (HDS) Research: Employed as a model reactant to study the efficiency and mechanisms of catalysts designed to remove refractory sulfur compounds from fuels.
• Organic Electronic Materials Research: Investigated as a potential building block or dopant in the synthesis of novel semiconductors and optoelectronic materials due to its fused aromatic structure.
• Analytical Method Development: Serves as a high-purity calibration standard for developing and validating chromatographic (HPLC, GC) and spectroscopic methods for sulfur speciation.
• Chemical Synthesis: Utilized as a specialized intermediate or precursor in the synthesis of more complex sulfur-containing organic molecules for pharmaceutical or material science applications.
