What Purity Levels of n-Heptane Do We Offer?


When sourcing n-Heptane from international suppliers, one of the most common questions buyers ask is: “What purity levels are available?” The purity of n-Heptane directly impacts its performance, safety, and suitability for various applications, from industrial solvents to pharmaceutical processes.

1. Common Purity Grades of n-Heptane

Suppliers typically offer n-Heptane in the following purity levels:

  • 95% Purity: Often used in industrial applications such as adhesives, coatings, and general solvents. Suitable for processes where ultra-high purity is not required.
  • 99% Purity: A widely used grade for laboratories, analytical applications, and some industrial uses. It balances cost and performance.
  • 99.5% Purity or Higher: High-purity n-Heptane is commonly used in pharmaceutical, electronic, and specialty chemical industries. This grade meets strict quality standards and is often accompanied by Certificates of Analysis (COA).

2. Why Purity Matters

  • Industrial Applications: Lower purity grades may contain hydrocarbons that do not affect general solvent performance but are unsuitable for sensitive processes.
  • Pharmaceutical & Laboratory Use: Impurities can affect reactions, product stability, or analytical accuracy. High-purity n-Heptane ensures consistency and compliance with regulatory standards.
  • Safety & Handling: Suppliers provide Material Safety Data Sheets (MSDS) indicating handling precautions for each grade.

3. How to Verify Purity

Before purchasing, buyers should request:

  • COA (Certificate of Analysis): Confirms the exact purity and identifies impurities.
  • MSDS (Material Safety Data Sheet): Provides safety and handling information.
  • Sample Testing: Some suppliers provide small sample shipments for testing in your own processes.

4. Choosing the Right Supplier

A reliable n-Heptane supplier should provide:

  • Clear documentation of purity levels.
  • International shipping options with proper packaging (ISO tanks, drums, pallets).
  • Compliance with certifications such as REACH, ISO, or GMP when required.

Conclusion

Understanding the purity levels of n-Heptane is critical for selecting the right grade for your application. Always request documentation and, if possible, test samples to ensure you receive the quality you need.

Ensuring REACH Compliance: n-Heptane in the European Market

Abstract:
n-Heptane (CAS 142-82-5; EC 205-563-8) is a registered substance under the European Union’s REACH regulation, enabling its safe and compliant use across diverse industries. As a mono-constituent substance of petroleum origin, n-Heptane is registered for tonnage bands exceeding 1,000 tonnes per year, ensuring wide availability for European buyers. The REACH registration dossier highlights its extensive applications, including as a solvent in manufacturing, a fuel additive, a component in coatings and adhesives, and in laboratory processes. Businesses sourcing n-Heptane in the EU should request REACH certificates, Safety Data Sheets (SDS), and confirmation of tonnage coverage from suppliers to guarantee regulatory compliance. For downstream users, verifying that specific applications are covered in the supplier’s dossier is crucial, while importers must ensure valid registration via their EU-based entity or Only Representative. With its robust regulatory framework and versatile uses, n-Heptane is positioned as a reliable, compliant, and high-value solvent and process material in the European market.


n-Heptane and REACH Registration in the EU

    • EC Number: 205-563-8
    • Typical Registration Number Format: 01-2119457603-38-xxxx
  • Substance Type:
    n-Heptane is registered as a mono-constituent substance, most commonly of petroleum origin.
  • Tonnage Band:
    Registrations cover >1,000 tonnes per year, reflecting its broad industrial demand.

Industrial Applications of n-Heptane

The versatility of n-Heptane makes it an essential material across multiple European industries. Key applications include:

  • Solvent in manufacturing processes – widely used in adhesives, coatings, and extraction processes.
  • Fuel and fuel additives – supporting clean combustion and blending.
  • Cleaning agents – valued for its efficiency in dissolving oils and greases.
  • Laboratory applications – as a reference solvent and calibration standard.
  • Formulations – incorporated into paints, coatings, and industrial adhesives.

Compliance Documentation for Buyers

To ensure smooth operations and full compliance, buyers in the EU should request the following documents from suppliers:

  1. REACH Certificate – official proof that the product is registered under REACH.
  2. Safety Data Sheet (SDS) – including the REACH registration number and hazard/safety guidance.
  3. Confirmation of Tonnage Coverage – assurance that the supplier’s registration covers the required quantity and intended use.

Obligations for Buyers in the EU

  • Downstream Users:
    Businesses that use n-Heptane in production must confirm that their applications are included in the supplier’s registration dossier. The SDS will provide this detail.
  • Importers:
    If n-Heptane is imported from outside the EU, the responsibility for REACH registration lies with the importer. Alternatively, the non-EU manufacturer can appoint an “Only Representative” to manage registration on their behalf. In both cases, importers should obtain the valid REACH registration number.

Conclusion

With full REACH registration, n-Heptane is a reliable and compliant material for European industries. Its wide-ranging applications, regulatory approval, and high-volume availability position it as a critical solvent and process chemical. By sourcing from trusted suppliers and ensuring the proper documentation, buyers can secure both regulatory compliance and uninterrupted supply.
