n-Hexane vs Hexane

What is the difference between hexane and n-Hexane?

Hexane is a general term for all structural isomers with the molecular formula C6H14. n-Hexane is the straight-chain isomer, consisting of six carbon atoms connected in a continuous chain.

Why are the terms sometimes used interchangeably?

In industry, “hexane” often refers to a mixture of isomers, usually containing a high proportion of n-Hexane. In scientific, contractual, or regulatory documents, “n-Hexane” is used to specify the exact compound and avoid ambiguity.

Do they have different physical properties?

n-Hexane has a boiling point of approximately 69 °C and a relatively narrow property range. Hexane mixtures have a broader boiling range, depending on the proportion of branched isomers.

How are they used in practice?

Hexane mixtures are commonly used in gasoline blending, solvents, adhesives, and cleaning agents. n-Hexane (pure) is widely used in vegetable oil extraction, laboratory solvents, and industrial cleaning.

How should they be specified in contracts or technical documents?

Use “n-Hexane” when referring to the straight-chain compound. Use “hexane” when referring to commercial solvent mixtures, but always include a specification sheet or certificate of analysis showing isomer composition. For clarity, include CAS number, purity level, and regulatory references where applicable.

Key Takeaway

Hexane is the umbrella term for all C6H14 isomers. n-Hexane is the straight-chain isomer, most relevant in industrial and regulatory contexts. Always distinguish between the two in technical or legal documents to ensure precision and compliance.

Dear Partners and Industry Colleagues in Vietnam,

We are honored to announce our participation in the Vietnam Medipharm Expo 2026, hosted by the Ministry of Health of Vietnam in Ho Chi Minh City.

Unlocking Market Opportunities in Vietnam

Vietnam is experiencing rapid growth in healthcare and pharmaceuticals. By 2025, the country’s healthcare spending is projected to reach USD 23.3 billion, with USD 2.3 billion dedicated to medical equipment alone. Yet, the industry remains heavily reliant on imports, and much of the infrastructure requires urgent modernization.

This creates strong demand for high-quality raw materials and precision manufacturing inputs. From pharmaceutical extraction and synthesis to medical device cleaning and analytical quality control, the choice of solvents directly impacts safety, efficacy, and compliance.
