High-Purity n-Heptane Manufacturer & Global Supplier (REACH Certified)
Welcome to Junyuan Petroleum Group, a top global n-Heptane manufacturer and reliable supplier of high-purity C7 hydrocarbon solvents. Because we make our goods to meet strict needs in active pharma ingredient (API) synthesis, fine chemical work, and precise lab tests, our n-Heptane lines deliver great batch consistency, ultra-low aromatic residue, and full global rule compliance.
As an established n-Heptane manufacturer, we proudly hold official EU REACH certification, which enables smooth export and full compliance across European and global markets. Therefore, whether you need top pharma grade n-Heptane (≥99.0% purity) for key extraction and crystal processes or high-volume industrial solvents for glue and rubber formulas, Junyuan Petroleum Group provides custom bulk transport and firm quality checks.
Core Advantages & Regulatory Compliance
- EU REACH Fully Registered: First, our full REACH status ensures a safe, legal supply chain for European pharma and chemical partners.
- Pharma Grade Excellence (≥99.0% Purity): In addition, our solvent is specially purified for API extraction, reaction media, and organic synthesis, featuring low non-volatile matter (NVM) and minimal aromatic impurities (≤10 ppm).
- Direct Factory Supply: Furthermore, we run advanced plant units as a direct n-Heptane manufacturer, so we ensure sharp factory prices, flexible order sizes, and quick lead times.
- Integrated Quality Control: Finally, our plants are fully certified under ISO 9001:2015 and ISO 14001:2015 standards, so we maintain strict step-by-step quality control from feedstocks to final drum packaging.

Key Applications of Our n-Heptane Solvents
1. Pharma Synthesis & API Extraction
In modern drug plants, global health groups strictly watch solvent purity. Consequently, our pharma grade n-Heptane acts as a key reaction solvent, extraction fluid, and purifying tool. Because of its ultra-low benzene and aromatic content, it helps drug makers easily follow strict ICH Q3C residual solvent limits.
2. Lab Testing & Analysis
Additionally, high-purity n-Heptane is widely used in lab setups. For example, it works as a mobile phase liquid for HPLC tests, a clear solvent in optical analysis, and a precise zero-point fuel mix in engine octane rating tests.
3. Adhesives, Coatings, and Fine Chemicals
Meanwhile, for rubber cement, glue mixes, fast-drying tapes, and special coating goods, industrial grade n-Heptane provides strong dissolving power. As a result, it yields smooth drying rates and lower health risks compared to harsh aromatic solvents.
Global Packaging & Export Logistics
As an experienced n-Heptane manufacturer exporting to over 50 countries, we supply safe, certified dangerous-goods (DG) packing options. Specifically, because n-Heptane has a low flash point, we strictly tailor our options to meet your shipping needs and fire safety rules:
- 200L Steel Drums: Net weight approx. 137 kg per drum; full container load (FCL) packing.
- ISO Tank Containers: 16.0 – 16.8 Metric Tons net capacity for large-scale industrial buyers.
Frequently Asked Questions (FAQ)
Q1: What makes Junyuan Petroleum Group a trusted n-Heptane manufacturer for the pharmaceutical industry?
A: As a direct n-Heptane manufacturer, we run dedicated high-purity distillation units producing pharma grade n-Heptane with purity ≥99.0%. In fact, our strict lab testing ensures ultra-low residue on drying and minimal aromatic levels (≤10 ppm), so we easily meet global pharma and API making standards.
Q2: Does your n-Heptane carry full EU REACH certification?
A: Yes. Junyuan Petroleum Group has completed full EU REACH registration for n-Heptane (CAS: 142-82-5). Therefore, European buyers can import our solvents directly without extra legal steps or volume limits.
Q3: Can I obtain a Certificate of Analysis (COA) and product sample prior to bulk ordering?
A: Absolutely. We provide batch COAs, Safety Data Sheets (SDS/MSDS), and test samples upon request. As a result, please contact our sales team to specify your purity grade and application needs.
