Product Description
3-Methoxythiophene is a sulfur-containing heterocyclic organic compound with the molecular formula C₅H₆OS and a molecular weight of approximately 114.17 g/mol. According to the available reference data, it is described as a transparent, light brown liquid. Its reported melting point is 49–50°C when crystallized from an ethyl ether/ligroin solvent system, and its boiling point is 80–82°C at 65 mmHg.
Featuring a thiophene ring with a methoxy substituent, 3-Methoxythiophene can serve as an intermediate in selected organic synthesis processes and the development of specialty chemical compounds. Potential applications in agrochemical, pharmaceutical, and fragrance-related research depend on the specific synthesis route and end-product requirements.
For industrial and laboratory use, product purity, physical properties, and storage conditions should be confirmed against the supplier's current technical data sheet (TDS) and Safety Data Sheet (SDS).
