n-Heptane Supplier China | CAS 142-82-5 | Industrial Solvent ≥97%

n-Heptane Product Overview

n-Heptane is a straight-chain C7 alkane used as a low-polarity, volatile solvent. It dissolves many oils, fats, rubber compounds and hydrocarbon materials and has a higher boiling point than n-Hexane. Commercial suitability depends on actual n-Heptane assay, boiling range, trace impurities, grade requirements and the controls available at the user’s site.

Typical Industrial Applications

• Cleaning and degreasing: controlled-system solvent for compatible metal parts and process equipment.
• Rubber and adhesives: process or formulation solvent for compatible elastomers and hydrocarbon resins.
• Extraction and purification: nonpolar solvent in selected validated industrial processes.
• Chemical processing: reaction, crystallization and carrier solvent where low polarity and a near-98°C boiling point fit the operation.
• Reference and analytical uses: high-purity grades are used in laboratories and octane-rating work, but industrial ≥97% material should not be represented as analytical grade.

n-Heptane vs n-Hexane

n-Heptane boils at a higher temperature and generally evaporates more slowly than n-Hexane. It does not share the same n-Hexane-specific EU Candidate List entry, but it remains a highly flammable hydrocarbon with occupational and environmental hazards. Substitution decisions should compare solvency, drying time, recovery energy, exposure limits, emissions, process validation and destination regulations rather than relying on one hazard statement.

COA and Grade Review

For industrial n-Heptane, compare actual assay and hydrocarbon composition, not merely “total heptanes.” Review distillation range, density, color, water, sulfur, benzene and non-volatile residue according to the process. Analytical or chromatography grades typically apply tighter water, UV absorbance and residue limits; high assay alone does not establish those grades.

Packaging, Storage and Safety

n-Heptane is highly flammable and its vapors can affect the central nervous system at elevated exposure. Package options depend on quantity, destination and dangerous-goods requirements. Store in closed compatible containers away from heat, ignition sources and strong oxidizers. Grounding, ventilation, vapor control and worker protection must follow the current SDS and site risk assessment.

Documents and Quotation Information

Provide assay, composition or boiling-range requirements, application, quantity, destination, packaging preference and required documentation. Xinchen can coordinate specification review, batch COA, SDS/TDS and export-feasibility confirmation.

Frequently Asked Questions

Is CAS 142-82-5 n-Heptane?

Yes. CAS 142-82-5 identifies normal heptane, the straight-chain C7 alkane.

Is ≥97% industrial material analytical grade?

No. Analytical grades require additional impurity, water, residue and sometimes UV-absorbance controls.

Can n-Heptane replace n-Hexane directly?

Not automatically. The different boiling point and evaporation rate require process, quality, safety and regulatory validation.

Safety note: n-Heptane is highly flammable. This page is general B2B information and does not replace the current SDS or occupational-exposure assessment.
