| Industry | Application | Process |
|---|---|---|
| Petrochemicals | Reference standard or calibration reagent | Used for qualitative and quantitative analysis in gas chromatography |
| Polymers | Plastic additive or solvent | Applied as a solvent or auxiliary plasticizer in polymer synthesis |
| Analytical Chemistry | Internal standard for chromatographic analysis | Employed as an internal standard compound in gas chromatography (GC) to enhance analytical accuracy |
| Environmental Monitoring | Contaminant reference sample | Used for detection of organic pollutants in environmental samples and method validation |
| Pharmaceutical R&D | Organic synthesis intermediate | Served as a starting material or model compound in the synthesis of long-chain alkanes |
| Test Item | Common Testing Method | Method Overview |
|---|---|---|
| Appearance | Visual Inspection | Place the sample in a clean, colorless glass test tube and observe its color and clarity under natural light. It should be a colorless, transparent liquid without suspended particles or precipitates. |
| Content (Purity) | Gas Chromatography (GC) | Using a capillary column (e.g., DB-5, HP-5) and FID detector, quantify the purity of heptadecane by comparing retention times and peak areas with those of standard substances. |
| Boiling Point | Distillation or Differential Scanning Calorimetry (DSC) | Determine initial and final boiling points via distillation; DSC can assist in measuring phase transition temperatures to verify whether the boiling range meets specifications (heptadecane boils at approximately 302–303°C). |
| Density | Densimeter or Pycnometer Method | Measure the liquid density at a specified temperature (e.g., 20°C) using a densimeter or pycnometer to verify consistency of the substance. |
| Refractive Index | Refractometry | Use an Abbe refractometer to measure the refractive index (n20D) at a specified temperature (e.g., 20°C) as an auxiliary indicator of purity. |
| Moisture Content | Karl Fischer Titration | Use a Karl Fischer titrator to determine trace moisture levels in the sample, preventing adverse effects on performance in applications such as reference materials or solvents. |
| Impurity Analysis | Gas Chromatography-Mass Spectrometry (GC-MS) | Combine GC’s separation capability with MS’s identification ability to detect and identify potential hydrocarbon impurities or other organic contaminants. |
| Sulfur Content | Ultraviolet Fluorescence or X-Ray Fluorescence | Measure total sulfur content to ensure compliance with high-purity reagent or fuel-grade standards (typically requiring very low sulfur levels). |
| Residual Solvents | Headspace Gas Chromatography (HS-GC) | Suitable for detecting low-boiling residual solvents (e.g., benzene, toluene) from manufacturing processes, ensuring product safety. |

1. How do you ensure product quality consistency?
We rely on a mature China-based manufacturing system and implement strict batch control and quality inspection for every shipment. Our production process complies with ISO 9001 standards, and a COA is provided for each batch to ensure consistent and reliable quality.
2. Do you offer competitive pricing for bulk orders?
Yes, as a China-based manufacturer and bulk supplier, we provide tiered pricing based on order volume. We support FOB and CIF quotations, as well as L/C payment terms for large transactions to meet international trade requirements.
3. Can you support large-volume or long-term supply?
We have stable production capacity and a well-established supply chain, enabling continuous bulk supply. We support ton-level and container-level orders, as well as long-term cooperation projects.
4. What is your typical lead time?
For in-stock products, shipment can be arranged within 1–3 days. For bulk packaging or customized orders, lead time depends on the specific quantity and production schedule.
5. What documents do you provide?
We can provide complete documentation upon request, including COA, SDS, TDS, and other compliance certificates, meeting industrial procurement and export requirements.
6. Can you customize product specifications or packaging?
Yes, we support customization of parameters such as purity, impurities, residual solvents, and heavy metals. We also offer various bulk packaging options, including 25kg bags, drums, and IBC tanks, suitable for industrial applications and transportation.
7. What shipping options do you support?
We support both FCL (Full Container Load) and LCL (Less than Container Load) shipments, and can flexibly arrange logistics solutions based on order size to meet bulk chemical export needs.
8. Do you provide technical or application support?
Yes, we provide basic application guidance and technical support based on industry experience to help customers optimize product usage.
9. How do you handle compliance and export regulations?
