2-(furyl-2)-ethanthiol acetate

2-(furyl-2)-ethanthiol acetate is a sulfur-containing ester known for burnt, onion, and mushroom flavor characteristics, used for informational reference rather than commercial fragrance or flavor applications.

General Material Description

2-(furyl-2)-ethanthiol acetate is a sulfur ether ester characterized by its chemical structure combining a furan ring with a thiol acetate group. It appears as a volatile, low-boiling liquid exhibiting burnt, onion, and mushroom aroma notes. Synonyms include 2-(2-furyl)ethanethiol acetate and 2-(2-furyl) ethane thiol acetate. It is catalogued in chemical databases such as PubChem, facilitating standardized reference. Sourced synthetically for analytical and research purposes, it is not commercially employed in flavor or fragrance formulations, serving predominantly as an informational compound in sensory chemistry.

Occurrence, Applicability & Potential Uses

This compound does not typically occur naturally but can be synthesized to explore sulfurous flavor profiles. It is primarily used for research and informational purposes concerning thiol esters with furan rings. Although similar compounds contribute to complex sensory notes in food and fragrance matrices, 2-(furyl-2)-ethanthiol acetate is not applied in commercial fragrance or flavor production. Its evaluation aligns with the safety and regulatory frameworks outlined in the FEMA (US) standards, which guide the usage and classification of flavor agents even if this specific compound is not authorized for such uses.

Physico-Chemical Properties Summary

2-(furyl-2)-ethanthiol acetate exhibits a boiling range of 100 to 103°C at a reduced pressure of 0.05 mm Hg, indicating significant volatility and a relatively low molecular weight. The presence of a thiol acetate functional group coupled with a furan moiety influences its stability and reactivity, particularly its susceptibility to hydrolysis and oxidation. Its sulfur atom imparts distinctive organoleptic properties, while the compound's volatility affects its detection threshold and formulation potential. These physicochemical characteristics dictate its behavior in sensory evaluations and analytical conditions rather than practical formulation use.

FAQ

What is 2-(furyl-2)-ethanthiol acetate and what are its sensory properties?
2-(furyl-2)-ethanthiol acetate is a sulfur-containing ester combining a furan ring with an ethanthiol acetate group. It possesses a burnt, onion-like, and mushroom aroma, contributing unique flavor characteristics. Despite its distinct sensory notes, it is primarily of interest for research and informational purposes rather than commercial flavor or fragrance production.
How is 2-(furyl-2)-ethanthiol acetate synthesized and where is it commonly found?
This compound is synthesized chemically in specialized laboratories to study sulfur-containing aroma compounds with furan rings. It is not commonly found in natural sources or typical consumer products. Its applications are limited to analytical research contexts rather than widespread commercial use, reflecting its volatile nature and distinctive sensory properties.
Is 2-(furyl-2)-ethanthiol acetate regulated for use in flavors or fragrances?
2-(furyl-2)-ethanthiol acetate is not approved or recommended for use in flavors or fragrances, as indicated by safety and regulatory sources including FEMA (US). There are no hazard classifications or precautionary label elements associated with it under OSHA HCS regulations. Its usage is confined to informational contexts, and it lacks established safety data for consumer exposure.
