n-Heptane 99% Technical

Product Overview

n-Heptane 99% Technical (CAS 142-82-5) is a highly refined, high-purity straight-chain alkane. This non-polar hydrocarbon solvent — widely utilized across various manufacturing and laboratory sectors — features excellent solvency power and predictable physical properties. Having a molecular formula of C7H16 and a molecular weight of 100.20, n-heptane is a clear, colorless liquid featuring a distinct gasoline-like petroleum odor. It is virtually insoluble in water, with a solubility of 0.0003 %, and is less dense than water with a density of 0.6838 at 68 °F, meaning it will float on the water surface.

In industrial chemical processes, maintaining a consistent 99% concentration is critical for ensuring reliable reaction chemistry and extraction yields. This technical grade heptane features a boiling point of 209.1 °F at 760 mmHg and a melting point of -131 °F, providing a stable liquid range for a variety of thermal conditions. Because its vapors are heavier than air and it possesses a low flash point of 25 °F, n-Heptane is an ideal quick-evaporating solvent for formulating fast-drying adhesives, coatings, and sealants. It leaves behind no greasy residue upon evaporation, ensuring a completely clean substrate.

Why This Grade

Selecting n-Heptane 99% Technical over lower-purity options is critical for processes that depend on strict non-polar solvent parameters. Technical grade heptane at a 99% minimum assay provides the essential chemical purity required for consistent manufacturing without the prohibitive cost of laboratory-reagent grades. Lower purity grades, such as 95% heptane, contain higher levels of branched isomers or aromatic hydrocarbon contaminants. These impurities can significantly alter the boiling profile, flash point, and overall solvency power of the chemical, leading to unpredictable evaporation rates and inconsistent formulation behavior in large-scale industrial operations.

The presence of excessive impurities in lower-grade solvents can lead to serious industrial failure modes. For instance, in extraction applications, residual aromatics from inferior grades can contaminate the final extract, compromising product safety and quality. In adhesive and coating applications, unwanted isomers can alter the drying time, resulting in poor adhesion, bubbling, or structural failures in the cured materials. By choosing our 99% technical grade, manufacturers minimize these risks, ensuring stable viscosity, uniform evaporation, and repeatable production results. It delivers the precise performance required for critical industrial workflows while optimizing raw material budgets.

Industrial Applications

• Industrial Extraction Solvent: Utilized in botanical and chemical extraction processes to cleanly separate non-polar compounds, oils, and fats from raw materials without dissolving polar impurities.
• Adhesives and Sealants Formulation: Serving as an essential fast-evaporating solvent carrier in the production of rubber cements, industrial adhesives, and contact glues to ensure quick dry times.
• Laboratory and Analytical Standard: Employed in testing laboratories as a non-polar solvent for chromatography, compound identification, and as a standard reference in octane rating processes.
• Paint, Coating, and Varnish Diluent: Acts as a diluent and solvent in industrial coatings, lacquers, and varnishes, enabling controlled viscosity adjustments and smooth, uniform application on substrates.
• Precision Cleaning and Degreasing: Used in metal fabrication and electronic manufacturing to remove grease, oils, and cutting fluids from machinery parts and sensitive components prior to finishing.

Hazmat & Shipping

n-Heptane 99% Technical is classified as a regulated hazardous material due to its high volatility and flammability. Under Department of Transportation (DOT) and international regulations, it must be shipped as UN1206, Hazard Class 3, Packing Group II under the proper shipping name Heptanes. The designated signal word for this chemical is Danger. To maintain complete safety and compliance, Alliance Chemical packages and transports this flammable liquid in strict accordance with DOT 49 CFR regulations, ensuring it is only moved by certified hazardous materials carriers.

Workers handling n-Heptane must wear appropriate Personal Protective Equipment (PPE) to protect against specific hazards associated with its GHS classification. To protect skin against irritation (H315), personnel must wear chemical-resistant gloves, such as nitrile or viton, and protective laboratory coats. Because inhalation of vapors can cause drowsiness or dizziness (H336), adequate local exhaust ventilation is required, and workers should use organic vapor respirators in confined spaces. Flame-resistant clothing and anti-static footwear should be worn to mitigate the risk of ignition from static discharge associated with its low flash point (H225). Please consult the Safety Data Sheet (SDS) provided with every order for comprehensive handling instructions.

Handling & Storage

Safe handling of n-Heptane 99% Technical requires strict environmental controls to prevent accidental ignition. Store this highly flammable liquid in a cool, dry, well-ventilated area away from direct sunlight, open flames, hot surfaces, and static electricity. Containers must remain tightly closed when not in use. Compatible materials for storage include steel, stainless steel, and high-density polyethylene (HDPE), while incompatible materials like certain rubbers and low-density plastics must be avoided as they will degrade. Keep the chemical segregated from strong oxidizing agents, chlorine, and concentrated acids to prevent dangerous exothermic reactions.
