Product Description
n-Heptane is an important nonpolar saturated alkane solvent classified as a Class 3 flammable liquid. It is a straight-chain alkane that is chemically stable, insoluble in water, and soluble in most organic solvents. n-Heptane is characterized by its low boiling point, low polarity, and high volatility, and is widely used in the pharmaceutical, chemical, electronics, and coatings industries.
For detailed information on the physical and chemical properties of n-Heptane, see 【Addition information】
