What is 2,2-dimethyl-5-(1-methylpropen-1-yl) Tetrahydrofuran?
2,2-dimethyl-5-(1-methylpropen-1-yl) tetrahydrofuran is a synthetic flavoring substance identified by the Chemical Abstracts Service (CAS) number 7416-35-5. It is an organic compound featuring a tetrahydrofuran ring structure—a five-membered oxygen-containing ring—with dimethyl and methylpropenyl substituents. This molecular configuration contributes to its sensory properties, particularly its aroma profile.
As a synthetic flavoring agent, this compound is manufactured through chemical synthesis rather than extracted from natural sources. The tetrahydrofuran class of compounds has been used in food flavoring applications for several decades, with some members of this chemical family appearing in various food products and flavoring formulations.
Common Uses
This additive functions as a flavoring agent or adjuvant in food manufacturing. It is used in small quantities to enhance or modify the taste and aroma of food and beverage products. Typical applications may include:
- Processed foods and snacks
- Beverages (both alcoholic and non-alcoholic)
- Confectionery and desserts
- Baked goods
- Flavored dairy products
The specific concentration levels used in foods are typically very low, generally in the parts per million (ppm) range, reflecting standard practices for synthetic flavoring agents.
Safety Assessment
According to available FDA records, there have been zero adverse events reported associated with this additive and zero recalls linked to its use. This absence of reported safety incidents suggests that at current levels of use, no acute or chronic health concerns have been documented through post-market surveillance.
The compound has not received GRAS (Generally Recognized as Safe) status from the FDA. GRAS status is a specific regulatory designation granted through petition or a qualified expert panel review process. The lack of GRAS designation does not necessarily indicate a safety concern; rather, it indicates that this particular substance may not have undergone the formal GRAS review process or may be used in applications where such designation is not required.
Limited published safety data is available in the scientific literature for this specific compound. As with many synthetic flavoring agents, safety assessments would typically consider toxicological studies, including acute toxicity, genotoxicity, and chronic exposure effects. The chemical structure suggests it would be metabolized similarly to other tetrahydrofuran derivatives by human enzyme systems.
Regulatory Status
Under current U.S. FDA regulations, this compound is not prohibited for use in foods. However, the specific regulatory pathway governing its use may depend on whether it is considered a direct food additive or a component of a flavoring preparation. Flavoring substances used in food are subject to FDA regulations but may have different approval requirements than other food additives.
Regulatory status may vary internationally. The European Food Safety Authority (EFSA) maintains separate approval lists for flavoring substances, and approval status in the European Union may differ from U.S. regulations.
Manufacturers using this ingredient must comply with all applicable FDA labeling requirements and ensure that the substance meets identity and purity specifications established for food ingredients.
Key Studies
Published peer-reviewed scientific literature specifically addressing this compound is limited. Safety assessments for synthetic flavoring agents in this chemical class typically rely on:
- Structural analogy studies with related tetrahydrofuran compounds
- General toxicological data for the chemical class
- Post-market surveillance data through FDA adverse event reporting
- Industry-sponsored safety dossiers submitted to regulatory agencies
The absence of reported adverse events and recalls in FDA records over the period this additive has been available suggests that current use levels present no documented safety concerns under normal conditions of use in food.
