What is 2-furanmethanethiol Formate?
2-furanmethanethiol formate (CAS Number: 59020-90-5) is a synthetic organic compound belonging to the class of furan-derived flavor compounds. It consists of a furan ring structure bonded to a methanethiol group and formate ester. This compound is classified as a flavoring agent or flavoring adjuvant and is used to impart complex savory, meaty, roasted, and cooked notes to food products. Like other furan-based flavoring compounds, it is volatile and contributes aromatic characteristics at extremely low concentrations.
Common Uses
2-furanmethanethiol formate is primarily employed in the food industry as a flavoring ingredient in processed foods where savory and umami taste profiles are desired. Common applications include:
- Meat and poultry flavored products
- Processed meat analogs and plant-based meat alternatives
- Savory snack foods
- Soup and broth seasonings
- Gravy and sauce preparations
- Bouillon products
This additive is used at very low concentrations—typically in the parts per million (ppm) range—making it economical and requiring minimal quantities to achieve the desired flavor enhancement. The formate ester form increases stability compared to the parent thiol compound.
Safety Assessment
2-furanmethanethiol formate has not been formally granted GRAS (Generally Recognized as Safe) status by the FDA, though this does not necessarily indicate a safety concern. The lack of GRAS status may reflect limited historical use in the United States food supply, limited safety data submissions, or application timing relative to regulatory processes.
The FDA's adverse event database contains zero reported adverse events associated with this compound, and there are no product recalls linked to its use. This absence of reported safety incidents suggests that if the compound is being used in food products, it has not generated consumer complaints or identified health problems at typical use levels.
The compound's chemical structure—a furan derivative—warrants note. Furan compounds have undergone safety scrutiny in recent years, though furan itself (found naturally in some foods) differs significantly from this synthetic derivative. The formate ester modification may affect absorption and metabolism compared to the free thiol form.
Regulatory Status
In the United States, 2-furanmethanethiol formate is not explicitly listed on the FDA's GRAS inventory, meaning it would require pre-market approval for use as a food additive under FDA regulations. However, it may be used in some jurisdictions outside the United States where different regulatory frameworks apply.
The European Food Safety Authority (EFSA) evaluates flavoring compounds through its flavoring evaluation program. Regulatory status in the European Union may differ from the United States.
Any manufacturer using this compound in food products intended for interstate commerce in the United States would typically need either GRAS status or an approved food additive petition. Current regulatory pathways remain open for submission of safety data to support potential approval.
Key Studies
Limited published scientific literature specifically addresses 2-furanmethanethiol formate's safety profile. Most flavoring compounds in this chemical class are evaluated based on their structural category, anticipated use levels, and metabolism patterns rather than individual extensive toxicology studies.
Safety assessments for similar furan-derived flavoring compounds rely on:
- Structure-activity relationship (SAR) analysis
- Anticipated exposure calculations
- Metabolic fate studies
- Comparative data from related approved flavoring agents
The absence of reported adverse events and regulatory recalls suggests acceptable safety margins at intended use levels, though comprehensive published toxicology studies specific to this compound appear limited in the public domain.
