Product Overview
n-Heptane 99% Technical is a high-purity, straight-chain alkane (C7H16) supplied as a colorless liquid. It is a primary non-polar solvent widely used in industrial and analytical applications due to its narrow boiling range (98.0–99.0 °C) and low viscosity. This technical grade solvent offers consistent solvency performance, making it essential for extraction processes, chromatography, and precision cleaning.
Engineered for reliability, n-Heptane 99% serves as a standard reference material for hydrocarbon analysis and supports rigorous sample preparation. Its low residue after ignition (<0.005%) prevents contamination in sensitive manufacturing and formulation workflows. The product is stored under inert conditions to maintain chemical integrity and is fully compatible with standard HDPE and glass industrial storage.
