N-pentane is an organic compound that appears as a colorless flammable liquid and is slightly soluble in ethanol, ether, and hydrocarbons. It is mainly used as a solvent, gas chromatography reference liquid, anesthetic, and can also be used to manufacture artificial ice, anesthetic, and synthesize pentanol, isopentane, etc.
N-pentane is used as a low boiling solvent, a foaming agent in the plastic industry, and together with 2-methylbutane, it is used as fuel for automobiles and aircraft, manufacturing artificial ice, anesthetics, and synthesizing pentanol, isopentane, etc; Gas chromatography analysis standard, used for the manufacture of anesthetics, solvents, low-temperature thermometers, as well as for the manufacture of artificial ice, pentanol, isopentane, etc; Used for preparing standard gas, calibration gas, and as a molecular sieve desorption agent; Used as a solvent, gas chromatography reference liquid, and anesthetic, as well as in organic synthesis and the manufacture of low-temperature thermometers.

N-Pentane should be stored in a cool and ventilated warehouse. Keep away from sparks and heat sources. The temperature of the warehouse should not exceed 29 ℃. Keep the container sealed. It should be stored separately from oxidants and should not be mixed for storage. The warehouse adopts explosion-proof lighting and ventilation facilities. Prohibit the use of mechanical equipment and tools that are prone to sparks. The storage area should be equipped with emergency response equipment for leaks and suitable storage materials.
Usually, the n-pentane is packaged by steel drums or ISO tanks, The packaging specifications are 125kg/drum, 14.0 Metric Tons/ ISO Tank.
