Description

2,2,7,7-Tetramethyloctane CAS NO 1071-31-4 is a highly branched, saturated hydrocarbon belonging to the class of alkanes. Its unique, symmetrical structure of four methyl groups confers exceptional chemical stability and makes it a valuable non-polar solvent and chemical intermediate. This compound is particularly sought after for applications requiring a high-purity, inert medium with specific volatility characteristics. Key industries that utilize this specialty alkane include advanced materials research, specialty chemical synthesis, and performance additive formulation.

Application

• Chemical Intermediate: Used in the synthesis of more complex organic molecules, including surfactants, lubricant additives, and specialty polymers, where its branched structure influences final product properties.
• Non-Polar Solvent: Serves as an inert reaction medium or extraction solvent in laboratory and industrial processes for materials sensitive to reactive or protic solvents.
• Reference Standard & Calibrant: Employed in gas chromatography (GC) and mass spectrometry (MS) as a high-purity reference compound due to its well-defined retention time and mass spectral characteristics.
• Performance Fluid Component: Investigated for use in high-stability hydraulic fluids, heat transfer fluids, and specialty lubricants where thermal and oxidative stability are critical.
• Research & Development: Utilized in academic and industrial R&D for studying hydrocarbon properties, reaction mechanisms, and as a model compound in physical chemistry.
• Additive for Fuels and Lubricants: Potential application as a component or precursor for additives designed to improve octane rating, reduce friction, or modify viscosity.
