High-Purity n-Heptane Industrial Raw Material Spot Supply Information

Introduction

n-Heptane of very high purity (CAS 142-82-5, C₇H₁₆) is a grade of straight-chain aliphatic hydrocarbon and non-polar solvent mainly used to dissolve different substances at the industrial level. With an ultra-low level of impurities, very narrow distillation range, excellent chemical inertness and consistent quality across different production lots, this substance is heavily used in areas such as pharmaceutical preparation, product inspection, polymer making, fine chemical production and natural product isolation.

Relative to n-hexane and a mixture or various forms of heptane, using this substance in a process can result in a lower risk of problems or process instability with high-quality manufacturing. When a company tries to get a supply of good-quality n-heptane overseas, it often has to deal with problems like a fluctuating level of supplies, a really slow delivery from a factory to the site, a non-verified quality of the product and very few options when it comes to transportation for such chemicals that are hazardous. Our company is ready to offer you at all times, only those items that have been tested and are of a good quality (spot inventory). We can deliver spot quantities of n-heptane to B2B manufacturers, laboratories and chemical traders around the world. You may learn more about product standards, usage, sales contracts, packaging, health and safety and placing orders with our company from this page which should simplify buyer evaluation and ordering processes by the buyers.

The Chemical and Physical Properties Characteristics of Product

n-Heptane is a colorless, transparent, very volatile liquid that has a mild smell. It does not dissolve in water but it is fully miscible with ethanol, ether, acetone and some hydrocarbon solvents. The reason it has the ability to dissolve the grease, lipids, etc., is because it is non-polar so, it will easily dissolve those things.

Our spot high-purity n-heptane is obtained only through very accurate distillation and purification which is one of the methods in obtaining high-purity substances. Also, each batch is strictly tested with GC and a COA certificate is issued with each product. Some of the basic technical indicators of this product are listed below.

CAS No.: 142-82-5 / EINECS No.: 205-563-8

Molecular Weight: 100.21 g/mol

Purity: ≥99.0% (Industrial Grade), ≥99.5% (Premium Grade)

Density at 20°C: 0.684 g/cm³ | Boiling Point: 98.4°C

Closed-cup Flash Point: -4°C | Melting Point: -90.5°C

Major Impurities:

- Total aromatics ≤50 ppm

- S sulfur ≤5 ppm

- Water ≤100 ppmDistillation Range: 97.0-100.0°C

Appearance: It's a clear, colorless liquid. It doesn't contain any kinds of solid particles.

Aromatic and sulfur constituents at very low levels virtually eliminate the occurrence of undesirable features, e.g., color changes, side reactions and contamination, therefore the product is most suitable for manufacturing and analytical applications with high-precision and strict control of ‍‌impurities.

Core Industrial Utilizations

1. Pharma and Nature-Based Product Extraction

Being a low-residue inert solvent, n-heptane is extensively used for pure substance isolation, plant extract obtaining, and separation of lipophilic substances. It is a safer alternative to n-hexane as it avoids the formation of neurotoxic byproducts and at the same time fulfills pharmaceutical as well as natural extract purification needs.

2. Analytical Test & Fuel Calibration

Internationally, it is recognized as the zero-octane reference fuel (RON=0). Hence, it serves as the basic measuring tool for anti-knock evaluation of gasoline. It is also used as a highly pure mobile phase and pretreatment solvent for GC and HPLC analysis at petroleum, food, and environ-mental labs.

3. Production of Polymeric, Paint, Ink, and Glue Products

Owing to the chemical inertness, it is used as a medium for polymerization of synthetic rubber. In the paint, ink and glue sectors, it is used to adjust viscosity, improve film-forming performance, and ensure the homogeneity of the product. It is recoverable by distillation, so it helps in reducing manufacturing and solvent costs effectively.

4. Precision Degreasing & Electronic Cleaning (High Purity Solvent)

Being a high-purity solvent, the composition efficiently washes away grease and residues on metal parts and electronic components without leaving non-volatile deposits so that it satisfies high-cleanliness requirements, semiconductor/pixoelectronic/precision cleaning processes, etc.

5. Fine Organic Synthesis

As an inert reaction medium that is stable with minimal decomposition, it is applicable at lower synthesis temperatures for organic synthesis. Its excellent chemical inertness and easy distillation recovery are great assets for continuous production in fine chemicals.
