Description

n-Heptane is a straight-chain alkane solvent with the chemical formula C₇H₁₆, known for its excellent volatility and low polarity. It serves as a critical non-polar solvent and reference standard in analytical chemistry and industrial processes. This high-purity hydrocarbon is essential for manufacturers and laboratories in the pharmaceutical, polymer, and electronics sectors requiring precise and reliable solvent performance.

Application

• Primary reference fuel component for determining octane ratings in gasoline.
• Key solvent for extraction, purification, and recrystallization processes in pharmaceutical API manufacturing.
• Diluent and cleaning agent in adhesive, rubber, and polymer production.
• Essential solvent for thin-layer chromatography (TLC) and gas chromatography (GC) applications.
• Reaction medium and solvent in organic synthesis and laboratory research.
• Cleaning and degreasing agent for precision parts in electronics manufacturing.
• Component in standard test mixtures and analytical reference materials.
• Industrial solvent for inks, coatings, and adhesive formulations.
