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

n-Heptane has been successfully registered under the EU’s REACH regulation (Registration, Evaluation, Authorisation and Restriction of Chemicals). The registration process ensures that the substance complies with stringent European standards for safety, environmental impact, and responsible use.

• Identifiers:
  • CAS Number: 142-82-5
  • 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.
