Industrial Applications
Heterocyclic and Specialty Chemical Intermediates
The benzothiophene ring system is a starting structure for substituted sulfur-containing aromatic compounds. Further functionalization produces derivatives for specialty chemical synthesis, depending on the reaction route and final molecular structure.
Pharmaceutical-Related Intermediate Synthesis
Benzothiophene structures occur in medicinal-chemistry compounds and pharmaceutical-related intermediates. CAS 95-15-8 is a chemical starting material, not a finished active pharmaceutical ingredient; suitability depends on the downstream process and its quality requirements.
Functional Organic Compounds
Substituted benzothiophenes have been studied in selected functional organic molecules, including conjugated structures. Final properties depend on the complete molecular structure and subsequent synthesis, not on the parent compound alone.
Send your assay target, analytical requirements, estimated quantity, packing preference and destination. The offered grade, MOQ, documents and schedule can then be confirmed.
Packaging and Commercial Supply
When requesting a quotation, you may specify a preferred pack size such as 1 kg, 5 kg or 25 kg. A 25 kg fiber drum is one format listed in the wider market for this chemical, but packing available for the offered Unilong grade must be confirmed before order placement.
For a trial or production order, include the required net weight and whether demand is one-time or recurring. MOQ, available quantity and pricing depend on the offered grade, packaging and order conditions; they are not assumed from competitor listings.
Dispatch timing is confirmed with the quotation and order arrangement. International transit time is additional and depends on destination, carrier and applicable transport requirements.
Storage, Handling and Transportation
Benzothiophene has a low melting range close to ordinary warm-weather temperatures. It may be received as crystals, fused solid, partially melted mass or liquid depending on temperature history. Assess physical appearance against the agreed specification and relevant batch documentation.
Use compatible, tightly closed packaging with an appropriate liner and secure sealing arrangement confirmed for the supplied material. Store in a suitable cool, dry and well-ventilated area, away from excessive heat and incompatible substances. Follow the SDS for the supplied grade and applicable transport regulations.
Quality Documents
Specify documents required for your purchasing process, such as a product specification, batch-specific Certificate of Analysis (COA) and Safety Data Sheet (SDS). Availability, test methods and results must be confirmed for the offered material and lot; this page does not imply that a specific batch COA is already available.
Frequently Asked Questions
What is the CAS number of benzothiophene?
Benzothiophene, also called Benzo[b]thiophene or Thianaphthene, has CAS number 95-15-8.
Can I request a specific GC purity for benzothiophene?
Yes. Include your required GC assay target and analytical method in the inquiry. The offered grade and batch specification must be confirmed in the quotation.
Can I request 25 kg drum packaging?
You can request a quotation for 25 kg drum packaging. The available pack type, liner, net weight and sealing arrangement are confirmed for the offered material before order placement.
What is the minimum order quantity?
The minimum order quantity depends on the offered grade, available quantity and packaging. Include your required net weight in the inquiry so the applicable MOQ can be confirmed.
Why can benzothiophene arrive in different physical forms?
Its melting point is approximately 28–32°C, so temperature changes can cause it to appear as crystals, fused solid or liquid. Assess the material against the agreed specification and batch documentation.
Can I request a COA and SDS?
Yes. State your document requirements in the inquiry. COA, SDS and analytical information availability are confirmed for the offered material and lot.
Provide your required assay, quantity, packaging preference, delivery destination and additional quality parameters.
