High-Purity Non-Polar Solvent for Chromatography, Extraction, and Hydrocarbon Analysis
VWR n-Heptane is a high-purity, straight-chain aliphatic hydrocarbon (H₃C(CH₂)₅CH₃) supplied under the AnalaR NORMAPUR® label, with a minimum assay of 99.0%, conforming to the standards required for analytical, chromatographic, and industrial-grade applications. It is widely used as a non-polar solvent in GC (gas chromatography), solvent extraction, gravimetric analysis, and reference fuel blending.
This clear, volatile liquid features a low boiling point, low density, and excellent hydrophobicity, making it ideal for hydrocarbon analysis, cleaning procedures, and organic compound purification. It is classified as flammable, irritant, harmful to health, and environmentally hazardous, requiring careful handling.
