1 6 Hexanediol Density
About 1 6 hexanediol density
Where to Source 1,6-Hexanediol Suppliers by Density Specifications?
Global supply of 1,6-hexanediol (HDO), a key diol used in polyurethanes, UV-curable resins, and cosmetic formulations, is concentrated among specialized chemical manufacturers primarily based in China. These suppliers operate within integrated industrial ecosystems focused on organic intermediates and fine chemicals, enabling precise control over physical properties such as density (approximately 0.99 g/cm³ at 25°C). Production clusters leverage proximity to upstream petrochemical feedstocks and downstream polymer processors, ensuring stable output and competitive pricing.
Suppliers demonstrate vertical integration in synthesis and purification processes, with many operating under GMP-compliant facilities equipped for batch distillation and crystallization to meet industrial, electronic, and cosmetic-grade purity standards. The availability of multiple grades—industrial, technical, and high-purity (>99%)—supports diverse formulation requirements where density consistency impacts viscosity, solubility, and reactivity. Buyers benefit from scalable production networks capable of fulfilling small trial orders (1 kg) up to bulk shipments (1+ tons), with lead times typically ranging from 7–15 days post-payment confirmation.
How to Evaluate 1,6-Hexanediol Suppliers for Quality and Reliability?
Selecting a reliable supplier requires rigorous assessment across technical, operational, and transactional dimensions:
Product Specification Accuracy
Confirm that suppliers provide verifiable data sheets detailing physical properties including density, melting point (41–43°C), and water content (<0.1%). For applications requiring strict formulation control—such as in adhesives or personal care products—demand GC or HPLC assay reports showing ≥99% purity. Cross-reference listed CAS number (629-11-8) across product listings to avoid misidentification with structurally similar alcohols like 1,2-hexanediol.
Manufacturing and Quality Infrastructure
Assess core production capabilities through available metrics:
- Facility size exceeding 3,000m² indicating capacity for continuous production
- In-house R&D teams supporting grade customization (e.g., low-color, low-acid value variants)
- Compliance with ISO 9001 or equivalent quality management systems
Prioritize suppliers advertising on-time delivery rates above 98%, which correlate with robust inventory management and packaging logistics.
Procurement Terms and Risk Mitigation
Analyze minimum order quantities (MOQs), which range from 1 kg for sample testing to 25 kg or 1 ton for commercial contracts. Favor suppliers offering tiered pricing aligned with volume commitments. Utilize secure payment mechanisms such as trade assurance programs to protect against non-delivery or specification discrepancies. Request pre-shipment samples to validate material characteristics before scaling procurement.

| Hebei Chuanghai Biotechnology Co., Ltd. | Daily Chemicals, Organic Intermediate, Chemical Reagents | US $10,000+ | 100% | ≤8h | - | 1 kg | $2.10–30 |
| Opq Chemical Co.,ltd | Organic Intermediate, Phosphate, Sulphate | US $10,000+ | 100% | ≤4h | 28% | 1 kg | $8–200 |
| Marchem Cn Co., Ltd. | Organic Intermediate, Alcohol & Ether, Amine Chloride | US $400+ | 100% | ≤2h | <15% | 10 pcs / 1,000 kg | $1.50–800 |
Performance Analysis
Unilong Industry and Jiangsu Suoteng lead in revenue generation and consistent on-time performance (≥98%), suggesting mature export operations and inventory planning. Marchem Cn Co., Ltd. stands out for ultra-fast response times (≤2h), critical for urgent sourcing cycles, though its lower online revenue indicates smaller-scale operations. Opq Chemical exhibits a notably higher reorder rate (28%), potentially reflecting customer satisfaction despite broader price dispersion. Price anomalies—such as $200/kg or $800/ton—highlight potential listing inconsistencies; buyers should confirm whether prices reflect pure 1,6-hexanediol or derivatives like 1,6-hexanediol diacrylate (HDDA).
FAQs
What is the typical density of 1,6-hexanediol?
1,6-Hexanediol has a density of approximately 0.99 g/cm³ at 25°C. This value may vary slightly depending on temperature and purity level. Suppliers should provide certified test reports if density-critical applications are intended.
How do I verify the chemical identity of 1,6-hexanediol?
Request full analytical documentation including FTIR, NMR, and GC-MS spectra. Confirm the CAS number 629-11-8 and molecular formula C6H14O2. Compare physical properties—melting point (41–43°C), boiling point (250°C)—with established reference values.
Can I obtain samples before placing a bulk order?
Yes, most suppliers offer 1 kg samples for evaluation. Some waive fees for qualified buyers or deduct sample costs upon subsequent orders. Allow 5–10 days for dispatch, depending on origin and shipping method.
Are there alternatives to 1,6-hexanediol with similar density profiles?
Yes, 1,4-butanediol (density ~1.02 g/cm³) and neopentyl glycol (~1.0 g/cm³) serve as functional substitutes in certain polymer systems. However, differences in reactivity and hydrophilicity require reformulation validation.
What packaging options are available for 1,6-hexanediol?
Standard packaging includes 25 kg fiber drums lined with PE bags or 1-ton jumbo bags for bulk orders. For laboratory use, HDPE bottles or aluminum pouches (100g–1kg) are common. Ensure packaging is moisture-resistant due to hygroscopic nature.
