FlavScents AInsights Entry for 5-(6-hepten-1-yl)dihydro-2(3H)-furanone

1. Identity & Chemical Information

Common Name(s): Not widely known by a common name
IUPAC Name: 5-(6-hepten-1-yl)dihydro-2(3H)-furanone
CAS Number: 854737-08-9
FEMA Number: Not available
Other Identifiers: Not available
Molecular Formula: C11H18O2
Molecular Weight: 182.26 g/mol
Functional Groups and Structure–Odor Relevance: This compound contains a furanone ring, which is often associated with sweet, caramel-like odors. The presence of an alkene side chain may contribute to its volatility and potential for a fresh, green note.

Citation hooks: FlavScents; PubChem; FEMA

2. Sensory Profile

Odor and Flavor Descriptors: The compound is characterized by a sweet, lactonic odor with nuances of coconut and creamy undertones. It may also exhibit a slight green, fresh note due to its unsaturated side chain.
Taste and/or Odor Thresholds: Not clearly reported; typical lactones have low odor thresholds, often in the ppb range.
Typical Sensory Role: It is likely used as an impact note or modifier in formulations requiring a creamy, coconut-like profile.

Citation hooks: FlavScents; peer-reviewed sensory literature

3. Natural Occurrence & Formation

Known Natural Sources: This compound is not commonly reported in natural sources but may be a synthetic analog used to mimic natural lactones.
Formation Pathways: Typically synthesized through chemical processes involving the cyclization of hydroxy acids or through the oxidation of unsaturated alcohols.
Relevance to “Natural Flavor” or “Natural Fragrance” Designation: As a synthetic compound, it may not qualify for natural labeling unless derived from natural precursors.

Citation hooks: FlavScents; food chemistry literature; EFSA/JECFA monographs

4. Use in Flavors

Flavor Categories and Applications: Primarily used in dairy, coconut, and tropical fruit flavor profiles.
Functional Role in Flavor Systems: Acts as a key impact note providing creamy, coconut-like characteristics.
Typical Use Levels: Industry-typical use levels range from 0.1 to 5 ppm in finished products, depending on the desired intensity.
Stability Considerations: Generally stable under typical food processing conditions but may degrade under extreme heat or acidic conditions.

5. Use in Fragrances

Fragrance Families and Product Types: Utilized in tropical, gourmand, and creamy fragrance compositions.
Functional Role: Serves as a modifier or impact note, enhancing creamy, lactonic aspects.
Typical Concentration Ranges: Used at trace levels up to 0.5% in fragrance formulations.
Volatility and Top/Middle/Base Contribution: Likely contributes to the middle note due to its moderate volatility.

Citation hooks: FlavScents; IFRA; fragrance chemistry texts

6. Regulatory Status (Regional Overview)

United States (FDA / FEMA GRAS): Not explicitly listed; usage should comply with general safety standards.
European Union (Reg. (EC) No 1334/2008; FL number status): Not specifically listed; compliance with general flavoring regulations required.
United Kingdom: Follows EU regulations post-Brexit with no specific divergence reported.
Asia (Japan, China, ASEAN): Not clearly reported; typically follows international safety guidelines.
Latin America (e.g., Brazil, MERCOSUR): Not specifically listed; general safety compliance assumed.

Citation hooks: FEMA; EFSA; national authority publications

7. Toxicology, Safety & Exposure Considerations

Oral Exposure: Data not found; typical lactones are considered safe at low concentrations with a wide margin of safety.
Dermal Exposure: Not reported; generally, lactones are not known to be primary irritants or sensitizers.
Inhalation Exposure: Volatility suggests potential for inhalation exposure; occupational safety measures should be considered.

Citation hooks: EFSA; FEMA; PubChem; toxicology literature

8. Practical Insights for Formulators

Why This Material is Valuable: Provides a unique creamy, coconut-like note that is difficult to achieve with other compounds.
Typical Synergies: Pairs well with other lactones, vanilla, and tropical fruit flavors.
Common Formulation Pitfalls: Overuse can lead to an overpowering or artificial taste.
Situations Where It is Frequently Over- or Under-used: Often under-used in non-dairy applications where a subtle creamy note is desired.

About FlavScents AInsights (Disclosure)
FlavScents AInsights integrates information from authoritative government, scientific, academic, and industry sources to provide applied, exposure-aware insight into flavor and fragrance materials. Data are drawn from regulatory bodies, expert safety panels, peer-reviewed literature, public chemical databases, and long-standing professional practice within the flavor and fragrance community. Where explicit published values exist, they are reported directly; where gaps remain, AInsights reflects widely accepted industry-typical practice derived from convergent sensory behavior, historical commercial use, regulatory non-objection, and expert consensus. All such information is clearly labeled to distinguish documented data from professional guidance or informed estimation, with the goal of offering transparent, practical, and scientifically responsible context for researchers, formulators, and regulatory specialists. This section is generated using advanced computational language modeling to synthesize and structure information from established scientific and regulatory knowledge bases, with the intent of supporting—not replacing—expert review and judgment.
