2. Sensory Profile

2-(1-propenyl) pyridine is known for its strong, tobacco-like odor, which can be described as smoky, woody, and slightly sweet. It is often used as an impact note in flavor and fragrance formulations to impart a realistic tobacco scent. The intensity of its odor is moderate to strong, making it suitable for use in both top and middle notes of fragrance compositions. Specific taste and odor thresholds are not clearly reported in the literature.

3. Natural Occurrence & Formation

2-(1-propenyl) pyridine is not commonly found in nature but can be formed through the Maillard reaction, a chemical reaction between amino acids and reducing sugars that occurs during the cooking of foods. This compound is relevant to the "natural flavor" designation when derived from natural processes or sources, although it is primarily synthesized for commercial use.

4. Use in Flavors

2-(1-propenyl) pyridine is primarily used in tobacco flavor formulations, where it serves as a key impact note to replicate the complex aroma of tobacco. It is also used in savory flavors to add depth and smokiness. Typical use levels in finished food or beverage products range from 0.1 to 5 ppm, depending on the desired intensity and application. It is relatively stable under typical processing conditions but may degrade under extreme heat or acidic conditions.

5. Use in Fragrances

In the fragrance industry, 2-(1-propenyl) pyridine is utilized in tobacco, leather, and woody fragrance families. It acts as a modifier and impact note, providing a realistic tobacco scent. Typical concentration ranges in fragrance formulations are from trace amounts up to 0.5%, depending on the desired effect. Its volatility allows it to contribute to both the top and middle notes of a fragrance composition.

6. Regulatory Status (Regional Overview)

United States: Not explicitly listed as FEMA GRAS; usage in flavors may be subject to general safety evaluations.
European Union: Not specifically listed under Regulation (EC) No 1334/2008; usage may be governed by general flavoring regulations.
United Kingdom: Follows EU regulations post-Brexit with potential for future divergence.
Asia: Limited specific information; usage likely subject to general flavor and fragrance regulations.
Latin America: Specific regulatory status not clearly documented; general safety and usage guidelines apply.

7. Toxicology, Safety & Exposure Considerations

Oral Exposure: Data not found for specific ADI or MSDI values; general safety evaluations apply.
Dermal Exposure: Limited data on irritation or sensitization; formulators should consider IFRA guidelines for similar compounds.
Inhalation Exposure: Volatility suggests potential for inhalation exposure; occupational safety measures should be considered.

Risk profiles may differ between food and fragrance applications, with fragrance use potentially requiring more stringent safety assessments due to dermal exposure.

8. Practical Insights for Formulators

2-(1-propenyl) pyridine is valued for its ability to impart a realistic tobacco aroma, making it a critical component in tobacco and smoky flavor profiles. It synergizes well with other smoky and woody notes but can easily overpower a formulation if used excessively. Formulators should be cautious of its intensity and potential for degradation under extreme conditions.

9. Confidence & Data Quality Notes

The data on 2-(1-propenyl) pyridine is well-established in terms of its sensory profile and typical applications. However, specific regulatory and toxicological data are less documented, indicating a need for formulators to rely on industry-typical practices and safety evaluations.

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.
