n-Heptane 99% Technical

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.

Safety & Handling

Hazmat Classification: UN 1206, n-Heptane, Class 3, Packing Group II.

This product is highly flammable and must be stored in a cool, well-ventilated area away from ignition sources. Use proper grounding techniques to prevent static discharge during transfer. Personnel should wear chemical-resistant gloves, safety goggles, and appropriate PPE to prevent skin and eye contact. In case of spill, use non-sparking tools and absorb with inert material. Refer to the Safety Data Sheet (SDS) for detailed exposure controls and emergency procedures.
