n-Heptane 99% ACS

Product Overview

n-Heptane 99% ACS is a high-purity, straight-chain alkane hydrocarbon that serves as an essential solvent and reagent in both industrial processes and laboratory environments. Characterized by its clear, colorless appearance and its distinct petroleum-like odor, this solvent exhibits highly predictable physical behaviors due to its 99% minimum assay. As a non-polar solvent, it is completely insoluble in water but highly miscible with most organic solvents, making it a critical choice for extraction procedures, chemical synthesis, and precision cleaning applications where moisture must be strictly avoided.

Alliance Chemical distributes this premium chemical within our hydrocarbons collection to meet the demands of facilities requiring consistent solvent performance. This specific grade of n-heptane is critical for applications that cannot tolerate the trace impurities found in lower-grade technical solvents, which can compromise reactions or leave residues on sensitive components. Whether used as a mobile phase in chromatography, an extraction solvent for natural products, or a baseline standard for octane rating determinations, our n-heptane delivers the reliability and chemical consistency demanded by modern industrial operations across North America.

Why This Grade

The ACS (American Chemical Society) grade designation guarantees that this n-heptane meets or exceeds the strict purity specifications established by the ACS Committee on Analytical Reagents. For processes that require a 99% concentration, utilizing a lower-purity technical or industrial grade introduces volatile organic compounds, branched isomers, and trace metals that can interfere with analytical results or poison catalytic systems. High-precision extraction and laboratory analysis demand this exact level of purity to ensure baseline stability and eliminate the risk of unwanted chemical side reactions that alter final product yields.

Selecting an incorrect grade of heptane can lead to catastrophic process failure modes, such as the deposition of non-volatile residues on precision mechanical parts, or cross-contamination in pharmaceutical solvent recrystallization. Lower-grade solvents often contain higher fractions of isomers or aromatics that alter the boiling point and evaporation rate, leading to incomplete solvent recovery and inconsistent extraction profiles. By standardizing on our 99% ACS grade, operators prevent these costly quality deviations, ensure compliance with standard operating procedures, and guarantee that the chemical's physical properties align precisely with expected technical parameters.

Industrial Applications

• Laboratory Chromatography: Utilized as a mobile phase solvent in liquid chromatography and gas chromatography to separate non-polar compounds with high resolution.
• Precision Extraction: Serving as an efficient extraction solvent for botanical oils, fats, and natural products without leaving harmful chemical residues behind.
• Adhesives and Sealants: Employed as a carrier solvent in the formulation of high-performance industrial adhesives, rubber cements, and specialized coatings.
• Metal Cleaning and Degreasing: Used in precision manufacturing to clean and degrease electronic components and mechanical parts without causing oxidation or corrosion.
• Chemical Synthesis: Acting as an inert reaction medium or solvent for organic synthesis, polymerizations, and organometallic reactions requiring non-polar environments.

Hazmat & Shipping

n-Heptane 99% ACS is a highly flammable liquid regulated for transport as UN1206, Hazard Class 3, Packing Group II, with the proper shipping name Heptanes. The signal word for this material is Danger. Standard safety protocols mandate that personnel handling this solvent wear appropriate personal protective equipment (PPE) to mitigate risks associated with its hazard statements. This includes chemical splash goggles, nitrile or Viton gloves to protect against skin irritation (H315), and flame-resistant clothing to safeguard against the severe fire hazard (H225). Due to the risk of aspiration (H304) and drowsiness or dizziness (H336) from vapor inhalation, operations must occur under a certified fume hood or in areas equipped with robust mechanical ventilation systems.

Because n-Heptane is highly toxic to aquatic life with long-lasting effects (H410), containment measures must be strictly enforced during transport and transfer. Our shipping procedures fully comply with DOT regulations, ensuring that all containers meet rigorous pressure and material compatibility standards. A Safety Data Sheet (SDS) is provided with every order to ensure that your safety officer and material handling team have direct access to comprehensive hazard and handling guidelines. All shipments are dispatched via certified hazmat carriers to guarantee safe, legal, and compliant transit to your facility.

Handling & Storage

Storage of n-heptane must occur in a cool, dry, well-ventilated area away from direct sunlight, open flames, and incompatible substances such as strong oxidizing agents, halogens, and strong acids. Ideal storage temperatures should be maintained within a controlled range, typically between 50°F and 85°F, to minimize vapor pressure buildup and prevent thermal expansion. Standard container compatibility requires the use of steel, stainless steel, or approved high-density polyethylene (HDPE) containers, while avoiding materials like natural rubber, neoprene, and low-density plastics that degrade upon contact. Grounding and bonding of all transfer equipment are strictly required to prevent electrostatic discharge, a critical risk given the product's low flash point of 25 °F.
