Description

1-Methyldibenzothiophene CAS NO 31317-07-4 is a high-purity, polycyclic aromatic sulfur heterocycle (PASH) compound, serving as a critical reference standard and synthetic intermediate. Its value lies in its defined structure, which is essential for calibration in analytical chemistry and as a building block for advanced materials. This product is primarily needed by research institutions, analytical laboratories, and specialty chemical manufacturers working in petrochemical analysis, materials science, and organic electronics.

Application

• Analytical Reference Standard: Used for the identification and quantification of sulfur-containing compounds in complex matrices like crude oil, diesel, and other petroleum fractions via GC-MS, HPLC, and other chromatographic techniques.
• Petrochemical Marker: Acts as a model compound in studies of hydrodesulfurization (HDS) processes to develop more efficient catalysts for producing cleaner fuels.
• Organic Semiconductor Research: Serves as a precursor or dopant in the development of novel organic electronic materials due to its conjugated thiophene-based structure.
• Chemical Synthesis: Utilized as a key intermediate for synthesizing more complex dibenzothiophene derivatives with tailored properties for pharmaceuticals or advanced polymers.
• Environmental Analysis: Employed in environmental forensics and monitoring to trace the source and degradation of sulfur-containing pollutants.
