n-Heptane 99% Technical

Product Overview

n-Heptane 99% Technical is a high-purity, straight-chain alkane with the molecular formula C₇H₁₆. It is supplied as a colorless liquid with a characteristic hydrocarbon odor and a low boiling point, making it an ideal non-polar solvent for demanding industrial and analytical applications. The product is characterized by a narrow boiling range (98.0–99.0 °C) and a low viscosity (0.39 cP at 25 °C), enabling efficient handling, rapid evaporation, and consistent solvency performance across batch runs. Its densities and speciation are tightly controlled to support reproducible results in processes where solvent properties directly influence extraction efficiency, chromatography mobile phase composition, and cleaning effectiveness. This Technical Grade specification aligns with industry expectations for solvent reliability in laboratory and manufacturing environments.

In addition to its primary solvent role, n-Heptane 99% Technical functions as a standard reference material for hydrocarbon analysis, supports sample preparation in HPLC workflows, and serves as a non-polar extraction solvent in pharmaceutical and industrial contexts. The product is maintained under inert conditions to minimize oxidation and degradation, and it is compatible with HDPE and glass storage containers to preserve chemical integrity. Meticulous specification of trace metals, halides, and moisture supports high-purity requirements essential for analytical accuracy and process safety.

Safety Precautions

First safety paragraph: Handle and store in a cool, dry, well-ventilated area away from heat, sparks, and open flames. Use containers made of HDPE or glass; ensure proper secondary containment and grounding during transfer. Wear appropriate PPE including chemical-resistant gloves, safety goggles, and flame-resistant lab coat or apron. Keep away from strong oxidizers and acids, and follow local regulatory requirements for flammable liquids.

Second safety paragraph: Observe exposure controls and emergency procedures consistent with the SDS. This product is classified as Flammable (H225) and can cause serious eye irritation (H319); it may cause drowsiness or dizziness (H336). In case of accidental exposure, follow standard first aid measures: flush eyes with water for several minutes, wash skin with soap and water, move to fresh air if inhaled, and do not induce vomiting if ingested. In the event of a spill, evacuate and ventilate the area, use non-sparking equipment, and absorb with inert material for proper disposal according to local regulations.
