Heptane, Extra Pure,

Heptane, Extra Pure

Description:

Heptane, Extra Pure is a hydrocarbon solvent with the chemical formula C₇H₁₆. It is a colorless, flammable liquid with a faint petroleum-like odor. Heptane is commonly used in laboratories and industrial applications for its solvent properties, particularly when a non-polar solvent is required. The "extra pure" grade of heptane refers to a high-purity form, typically containing minimal impurities and used in sensitive applications where purity is critical.
