furfuryl thenyl ether

Furfuryl thenyl ether is a chemical compound known for its woody, green, elderberry-like odor used mainly for informational research rather than fragrance or flavor applications.

General Material Description

Furfuryl thenyl ether, also known as 2-(thiophen-2-ylmethoxymethyl)furan, is an organosulfur compound displaying a molecular formula of C10H10O2S and a molecular weight near 194.25 g/mol. It exhibits a woody and green aroma reminiscent of elderberry when diluted at one percent in dipropylene glycol. This compound is distinguished by its fused furan and thiophene ether structure. Available chemical data links include its PubChem entry which details its molecular structure and physicochemical characteristics. Sourced primarily through laboratory synthesis involving thiophene and furanyl precursors, furfuryl thenyl ether remains primarily a subject of chemical information rather than commercial fragrance or flavor use.

Occurrence, Applicability & Potential Uses

Furfuryl thenyl ether is not reported as naturally occurring in biological systems but represents an artificial chemical intermediate. Its main utility resides in research contexts focused on odorant characterization rather than direct commercial application. Safety and regulatory reviews, such as those covered by REACH (European Union), indicate no classification or registered uses for fragrances or flavorings. This ether's sensory attributes suggest potential utility for fragrance modification; however, official recommendations restrict its use to informational purposes only, reflecting precaution in consumer product formulations.

Physico-Chemical Properties Summary

The compound is moderately soluble in water, with an estimated solubility of approximately 244 mg/L at 25 °C, indicating limited but noteworthy polarity likely due to its ether and furan functionalities. Its estimated partition coefficient (xlogP3-AA) of 1.90 predicts moderate lipophilicity, influencing interaction with both aqueous and lipophilic environments. These properties suggest potential compatibility with various solvent systems, though its physical stability and reactivity are tailored by the aromatic heterocyclic rings containing oxygen and sulfur atoms. Such characteristics impact formulation considerations where odor profile consistency and solvent miscibility are critical.

FAQ

What is furfuryl thenyl ether and what are its main characteristics?
Furfuryl thenyl ether is a chemical compound identified by the formula C10H10O2S, featuring a combination of furan and thiophene rings linked via an ether group. It emits a woody, green odor with subtle elderberry-like nuances when diluted appropriately. Chemically, it is noted for moderate water solubility and mild lipophilicity. The compound is known primarily through chemical research and is not commonly used in commercial fragrance or flavor products.
How is furfuryl thenyl ether used and where is it typically found or synthesized?
Furfuryl thenyl ether does not have documented natural sources and is primarily synthesized for chemical studies focusing on odorant properties. It has limited to no application in flavor or fragrance manufacturing due to safety and regulatory considerations. Its preparation involves chemical reactions incorporating thiophene and furanyl building blocks. Currently, it serves an informational role within scientific databases and research rather than practical formulation contexts.
What safety and regulatory information is available for furfuryl thenyl ether?
No hazard classifications under the Globally Harmonized System (GHS) or OSHA regulations have been identified for furfuryl thenyl ether, reflecting limited safety data and non-commercial usage. Regulatory bodies, including those enforcing REACH standards in the European Union, do not list it for fragrance or flavor use, and manufacturers typically recommend against such applications. Toxicological profiles including oral, dermal, or inhalation toxicity remain undetermined, suggesting cautious handling and use strictly for informational or laboratory purposes.
