n-Butane is a nonpolar four-carbon alkane with the molecular formula C4H10. It is a gas at standard temperature and can be compressed to liquid for easy transport. n-Butane is a by-product of natural gas processing and petroleum refining and is commonly used in the welding industry and for instrument calibration. Similar to isobutane and propane, n-butane is one of a group of liquefied petroleum gases (LPG).
99.5% Instrument Grade n-Butane and is ideal for instrument calibration.
