TRIMETHYLPENTANE Chemical compatibility with O-rings, rubbers, & plastics

Trimethylpentane, also known as iso-octane, is a colorless liquid with the chemical formula C8H18, used primarily as a reference standard in the octane rating scale for gasoline. It is employed in various industrial and chemical applications, including the production of high-octane fuels and the calibration of analytical instruments. Trimethylpentane is also used as a solvent and in the manufacture of specialty chemicals. Proper handling and storage of trimethylpentane are essential to maintain its quality and prevent accidents, as it is highly flammable and can pose health risks if inhaled or ingested. Safety measures, including the use of appropriate protective equipment and adherence to handling protocols, are crucial when working with trimethylpentane. Its effectiveness as a reference standard and its unique properties make trimethylpentane a valuable chemical in numerous industrial and chemical applications, contributing to the synthesis and production of high-octane fuels and other products.
