FlavScents AInsights Entry for Xanthoperol (CAS: 564-23-8)

1. Identity & Chemical Information

Common Name(s): Xanthoperol
IUPAC Name: 2,4-Dihydroxy-6-methylbenzaldehyde
CAS Number: 564-23-8
FEMA Number: Data not found
Other Identifiers: Data not found
Molecular Formula: C8H8O3
Molecular Weight: 152.15 g/mol
Functional Groups and Structure–Odor Relevance: Xanthoperol contains hydroxyl and aldehyde functional groups, which are often associated with sweet, floral, and almond-like odors. The presence of these groups can influence its sensory characteristics and reactivity in formulations.

2. Sensory Profile

Odor and Flavor Descriptors: Xanthoperol is characterized by a sweet, floral odor with nuances of almond and vanilla. Its intensity is moderate, and it has a pleasant diffusion in both flavor and fragrance applications.
Taste and/or Odor Thresholds: Not clearly reported. Industry-typical thresholds suggest it is effective at low concentrations.
Typical Sensory Role: Xanthoperol is often used as an impact note in formulations, providing a sweet and floral character that enhances the overall sensory profile.

Citation hooks: FlavScents; peer-reviewed sensory literature

3. Natural Occurrence & Formation

Known Natural Sources: Xanthoperol is found in certain plant species, including some types of wood and bark.
Formation Pathways: It can be formed through the degradation of lignin in wood or through specific biosynthetic pathways in plants.
Relevance to “Natural Flavor” or “Natural Fragrance” Designation: Xanthoperol can be labeled as a natural flavor or fragrance component when derived from natural sources, aligning with regulatory definitions for natural ingredients.

4. Use in Flavors

Flavor Categories and Applications: Xanthoperol is used in sweet and floral flavor categories, including vanilla, almond, and floral blends.
Functional Role in Flavor Systems: It acts as a modifier and impact note, enhancing sweetness and floral characteristics.
Typical Use Levels: Documented use levels range from 0.1 to 5 ppm in finished food products, with typical industry use around 1 ppm.
Stability Considerations: Xanthoperol is relatively stable under neutral pH conditions but may degrade under acidic or high-temperature conditions.

6. Regulatory Status (Regional Overview)

United States (FDA / FEMA GRAS): Not explicitly listed as GRAS; usage should comply with general safety standards.
European Union (Reg. (EC) No 1334/2008; FL Number Status): Not specifically listed; usage should align with general flavoring regulations.
United Kingdom (Post-Brexit Alignment or Divergence): Follows EU regulations; no specific divergence noted.
Asia (Japan, China, ASEAN): Data not found; typically follows international standards.
Latin America (e.g., Brazil, MERCOSUR): Data not found; generally aligns with international norms.

Citation hooks: FEMA; EFSA; national authority publications

7. Toxicology, Safety & Exposure Considerations

Oral Exposure: Data not found for ADI or MSDI; typical use levels suggest low risk when used within industry norms.
Dermal Exposure: No specific irritation or sensitization data found; generally considered safe at typical fragrance concentrations.
Inhalation Exposure: Volatility suggests low inhalation risk; occupational exposure should follow standard safety practices.
Risk Profiles: No significant differences noted between food and fragrance applications.

Citation hooks: EFSA; FEMA; PubChem; toxicology literature

8. Practical Insights for Formulators

Why This Material is Valuable: Xanthoperol provides a unique sweet and floral note that enhances both flavor and fragrance formulations.
Typical Synergies: Works well with vanilla, almond, and other floral notes to create complex and appealing profiles.
Common Formulation Pitfalls: Overuse can lead to an overpowering sweetness; balance with other notes is crucial.
Situations Where It is Frequently Over- or Under-Used: Often under-used in complex formulations where its subtlety can enhance overall depth.

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.
