Tetrahydrofuran (THF) CAS 109-99-9 is a widely used cyclic ether solvent in industrial formulation and organic synthesis. For buyers, THF is not only a line item in a chemical catalog; it is often part of a production workflow where solvency, water content, stabilizer status, packaging integrity and export documentation all affect whether the material is suitable for use.
This guide introduces common THF application scenarios, specification checks and practical procurement points for global B2B buyers comparing industrial-grade solvent supply.
Common Application Scenarios
THF is valued because it can dissolve many organic materials and can work as a polar aprotic solvent in synthesis and formulation. In industrial purchasing, buyers often evaluate THF for the following scenarios:
- Polymer and resin processing: THF is commonly reviewed as a solvent for polymers and resins, especially where strong solvency and clear dissolution behavior are required.
- Coatings, inks, adhesives and lacquers: Formulators may compare THF for viscosity adjustment, resin compatibility, wetting behavior and drying balance in coating or adhesive systems.
- Organic synthesis: THF is often considered as a reaction medium in fine chemical, pharmaceutical intermediate, agrochemical and specialty chemical synthesis. Water content and inhibitor/stabilizer status may be important depending on the process.
- Extraction and cleaning processes: In selected industrial processes, THF may be evaluated for solvency, residue, evaporation behavior and compatibility with process materials.
- Pilot trials and supplier qualification: Buyers may request small trial quantities first to compare batch consistency, odor, color, moisture and COA values before regular procurement.

Why THF Specifications Matter
For many downstream users, simply confirming the product name is not enough. THF quality should be checked against the intended application. A coatings buyer may care about odor, residue and resin compatibility, while a synthesis buyer may focus more on water content, purity, stabilizer status and batch consistency. If the product is used in a sensitive formulation or reaction system, buyers should confirm the current batch COA before arranging shipment.
Useful purchasing details include target purity, moisture limit, preferred stabilizer status, packaging format, destination port, storage plan and whether the material will be used for formulation, cleaning, extraction or synthesis. Sharing these details helps the supplier confirm whether the available grade is suitable.
Packaging, Storage and Handling Notes
THF is a volatile solvent and should be handled according to the latest SDS for the exact batch. Buyers should review storage temperature, ventilation, ignition-source control, container sealing and compatibility with other materials. For longer storage or sensitive applications, stabilizer status and peroxide-related controls may need to be reviewed according to the buyer’s internal safety procedure.
Packaging should be selected according to order quantity, destination rules and warehouse conditions. Common export discussions include drum packaging, palletization, container loading, labeling, batch identification and document preparation.
Documents to Confirm Before Shipment
For international procurement, buyers usually ask for SDS or MSDS, COA, TDS and export-related documents. Depending on destination and shipping route, dangerous goods classification, UN number, hazard class, packaging group, carrier acceptance and customs document requirements should be reviewed before shipment planning.
How to Request a Faster Quotation
For a faster THF quotation, send the product name, CAS number, required purity, target application, quantity, destination country or port, preferred packaging and required documents. If the product will be used in a reaction, formulation or electronics-related process, include any moisture, stabilizer, residue or impurity limits you need to compare.

Turning a grade description into an approved specification
THF is a volatile ether solvent valued for broad solvency and miscibility with water. It can form peroxides during storage, so inhibitor status, storage history and peroxide-control procedures belong in technical qualification alongside assay and water.
Define the actual end-use requirement first. The specification should identify critical parameters, numeric limits, units, methods and the physical form or inhibitor system where relevant. A grade name is useful for initial screening, but final approval should be based on measurable requirements and a representative sample.
Core parameters for Tetrahydrofuran (THF)
| Review point | Practical action |
|---|---|
| assay and identity | Specify limit, unit and method; compare the shipping-batch result. |
| water content | Specify limit, unit and method; compare the shipping-batch result. |
| peroxide result and test timing | Specify limit, unit and method; compare the shipping-batch result. |
| inhibitor status where applicable | Review when relevant to the approved process and destination. |
| colour, acidity and non-volatile residue | Review when relevant to the approved process and destination. |
Results must be interpreted as a group. A strong assay result does not cancel an unsuitable water, residue, inhibitor, acidity or impurity result. Method details matter as well: sample handling, calculation basis and reporting limits can change whether two COAs are genuinely comparable.
Sample approval and incoming inspection
For a new supplier or changed grade, request a current specification, representative COA and SDS before ordering. Test a representative sample using the receiving plant’s normal method and, where performance is process-sensitive, complete a documented laboratory or pilot trial. Record the approved grade, critical limits and acceptance decision.
Before shipment, review the actual batch COA. On receipt, verify package condition, product identity, lot number, net weight and required labels before sampling. A retained sample and receiving record make later quality investigations more reliable.
Commercial and logistics checklist
- Confirm product name and CAS number: Tetrahydrofuran (THF), 109-99-9.
- State grade, required specification, quantity and intended application.
- Agree package type, net weight and unloading requirements.
- Review the latest SDS and transport classification for the supplied grade.
- Confirm destination port or country, Incoterm and required export documents.
- Approve a sample and the shipping-batch COA before regular use.
Storage and handling must follow the latest SDS, local regulations and the buyer’s process-hazard review. Online procurement information is not a substitute for an operating procedure, exposure-control plan or legal advice.
Product page and quotation details
See the current Tetrahydrofuran (THF) product page. A useful quotation request should include grade, critical limits, quantity, package preference, application, destination and required documents. Xinchen can then review the offered material and route without implying suitability beyond the documented specification.
